A Comedy Of Ages

 
The particulars of the Senpai/Kouhai character are firmly rooted in the way Japanese culture emphasises social hierarchy. As such they are only really found in visual novels developed in Japan and absent in the rest of the world unless they are trying to imitate that style. Yet despite this factor it is an extremely prolific type of character in the medium and has developed its own language of traits and expectations. At the centre of the Senpai/Kouhai character’s world is the protagonist since it in relationship to them that their status is decided and with it all sort of power dynamics. When romance gets added to the mix the differing ages of the characters involved start to come to the forefront and plays a role in shaping how they react and develop until a balance between them can be established. Being so popular has lead to certain character traits solidifying as being expected from these archetypes which reflect both their age and seniority. These troupes have formed into a strong part of their core appeal with many visual novels with a school setting leaning heavily into this desirability. Let’s greet our Senpai/Kouhai and uncover how a seemly dry element of social hierarchy became so popular.
 

Power Dynamics

 
Since the Senpai/Kouhai owes their identity to their social position in relation to the protagonist, there is a strong element of hierarchy to how they are presented within the story. While it is rare for them to abuse their position to compel the protagonist, they still engage in acts appropriate for their status and form an initial relationship with the protagonist through this lens from which they can build out into whatever form needed by the narrative. Schools provide the most common and easy to understand version of this use of status so this setting will be the primary source of examples for this phenomenon. For the Senpai their status is born from the seniority of age and this is reflected in the positions they occupy such a club or student council president. These titles immediately present an air of authority to the player and set an easy baseline for their interactions with the Senpai. In addition they offer a simple source of friction between the Senpai, their responsibilities and their own wishes which is a great basis for a character arc. Amaha Miu, from Mashiro-iro Symphony, is the president of the Nuko club and has to grapple with running it including financing it through her own part-time job. As such it plays a major role in her story since as a third year student she will soon have to leave it behind and when the protagonist joins it helps create a baseline for their banter and mutual respect. Despite being a gentle character Miu does pull rank on the protagonist on occasion out of concern for him and this soft power provides a good sense of her maturity in comparison to the protagonist since she understand when and how to use her authority. Another Senpai style character who has notable authority is Charles Maroth, from Da Capo III, the student council president. Being in the highest student position gives her an authority over the rest of the cast and the way they talk with her often reflects this respect. This makes her rivalry with her vice president Ricca stand out to the player as it undermines the initial universal respect the player would expect and creates a curiosity the game can capitalise on later. Playing with how this authority is thought about by others takes the edge of this power and provides an avenue for her weaknesses to come through without completely ruining her Senpai role. 
She is not the sharpest tool in the box

As for the Kouhai, their position is that of the inferior and subordinate and rely on the protagonist as their Senpai to act as their senior and a responsible individual. This is not the same as them being weak and incapable but rather an understanding of social status within the school structure even if they can be somewhat cheeky at times due to their youth. A common strategy to create drama is to play up this youthfulness as a kind of ignorance and have the Kouhai make a big mistake due to overconfidence or not listening to their Senpai. Toumine Tsukasa, from Irotoridori no Sekai, looks up to the protagonist as their Senpai and sees them as a source of wisdom. Her high energy and ignorance about the world highlight their youth and the role which the protagonist takes in protecting them and acting as a guiding point or senior. There is a definite over-exaggeration of the Kouhai identity in Tsukasa for the purposes of comic effect given she is so gullible to be beyond simple inexperience, but it still achieves the desired effect of the player wanting to make sure she does not come to any harm. A Kouhai’s respect can be merely performative as is the case with Arimura Hinae, from Chaos;Child, who only ever invokes her status as the protagonist’s Kouhai when it is convenient for her or as a sign of mockery. She is a character whose disrespect and confidence are a sign of her immaturity and they end up coming back to bite her when she pushes her luck due to this trait then needs to be bailed out. It also works as a means of establishing her weakness through an already present social dynamic and so make it feel more like an organic exploration of her and the protagonist’s changing relationship.
 

Romance Takes The Wheel

 
Once the Senpai/Kouhai has entered into a romantic relationship with the protagonist their dynamic shifting to accommodate this change. At this point the seniority element of their interactions becomes an uncomfortable issue to be worked around and most games aim to have it disappear into the background to avoid any problematic abuses of power within their romance. What often ends up happening is the playing up of the relative maturity of the Senpai/Kouhai as a source of endearment or comedy to take the edge off their previous dynamic. This can lead to a reduction in the emotional complexity of said character if not handled well since it is the removal or simplification of a core aspect of their identity. Even outside of romance the seniority element often finds itself sidelined in favour of other kinds of drama when it is not the story’s core focus for similar reason. It makes the inclusion of such a character outside of a main heroine role potentially problematic due to lack of time to smooth over their transition into what the narrative needs of them. 
You can just hear the 'Ara Ara'

For a Senpai example of this tendency, Renjouji Mai, from Secret Agent, can showcase an attempt to reconcile this friction. Her role as a Senpai and Captain of the Knights is a major focus of her initial introduction and relationship with the protagonist. Yet once the player enters her route this aspect almost instantly disappears when it concerns the protagonist as the game tries to rebalance their connection into a suitable romantic one to meet the needs of the romance genre. She morphs into more of a doting older sister kind of character where the age difference is merely an extra avenue for her to express her love for the protagonist. However, her seniority and its burdens still remain unchanged within the context of the dramatic plot points and her character development. This results in a weird sense of whiplash between how important her status as Senpai is to the story and to the protagonist with a stark line drawn to divide these elements. It feels like the game is trying to have its cake and eat it and highlights how blending romance and the need for drama using the Senpai role can be a challenge to keep coherent. Andou Misaki, from Chrono Clock, is a Kouhai who can demonstrate the opposite extreme manner visual novels handle this transition into romance. Rather than a sharp cut off, her loss of Kouhai status is a gradual process used to further the idea of her bond with the protagonist becoming closer and the barriers between them dissolving. On the other hand the game does not use her Kouhai aspects for any narrative purposes so it remaining prominent could have clashed with the character growth she undergoes. The issue with this approach is the way the Kouhai role almost feels redundant since it is neither a strong selling point for her character nor important for her arc and the player may feel cheated or confused at this shift in her personality. Neither of these attempts to deal with the Senpai/Kouhai relationship as part of romance can deal with the fundamental issues brought about by the imbalance in power between the relationship’s participants. They can only paste over the cracks and try to move away from it as smoothly as possible.
 

Confident, Teasing and Energetic

 
Having such a specific social relationship with protagonist has resulted in the Senpai/Kouhai character developing a number of personality archetypes and traits to meet the audience’s expectations. These work as a shorthand for the normal elements of this dynamic and aim to shape it into a desirable trait for the players to become attached to as they interact with the character. It also creates a common design language of their place within the player’s understanding of the archetype in a new visual novel. Let us go through a few of the most common traits or combinations to see this influence in action. In Shigure Asa, from Shuffle!, can be seen the outgoing and mischievous Senpai archetype where her maturity gives her the wisdom to outplay the protagonist in social situations while being generally liked by all and gets involved in their problems. There is a strong emphasis in her maternal personality through the care she gives others and the mixture of domestic skills from her participation on the cook club with the confidence she outwardly presents to others. What makes this appealing is the way Asa ends up revealing her vulnerability alongside her strengths and her teasing ends up being played on her instead for an entertaining swapping of roles and a humanising which differs from her self-presentation. The maturity of the Senpai is important to their traits and Ciel, from Tsukihime, showcases how that wisdom can be played up to make for a loveable character. She is a gentle and knowledgable person as befits her status as the protagonist’s Senpai and is always there to be a rock they can rely on in the face of chaotic events. This stability gives her a kind of soft power through the wisdom she can offer and how she presents it to the protagonist while being able to gently and powerfully suggest he does not do anything reckless. Even if the protagonist might not follow her guidance she is still willing to step in to help and, even has her less altruistic motives come to light, she cannot help but do what is right due to her sense of responsibility demanding it. 
She is everything the protagonist is not

Unlike the Senpai, a Kouhai can have a larger range of their initially presented personalities since their youth or inexperience allow them to openly have a weakness on display. The twins Himeyuri Sango and Ruri, from ToHeart2, are good examples of the breadth of traits present within the archetype. Sango is naive and has quite a child like attitude towards the world around her and the people she interacts with. It a curiosity and lack of world experience which would be expected from someone young so it triggers the player’s desire to protect her from mistakes she might make. Yet this does not exclude her from being able to display intelligence in matters of being an older sister and her work maid gynoids since it does not directly contradict the worldly wisdom she lacks. In contrast to her is Ruri who is the younger of the twins and prone to outbursts of emotion and possessiveness especially when it concerns Sango. This lack of control over her emotions is due to having not developed proper self control yet and communicates clearly the state of her development into an adult. Just like Sango’s naivety, this speaks to a time in our lives where we were the same while invoking the idea of this time in her life as being precious and worth turning the other check when she lashes out. As the extremes of the Kouhai spectrum they make for perfect twins since the player gets to enjoy the complete Kouhai experience. The Kouhai’s wide-eyed and naive beliefs in the good of the world can also function as a counterpoint to the protagonist’s cynicism such as with Claris Zeinburg, from Meteor World Actor. She is a fresh faced rookie and still possesses faith in the good their work is doing and acts on this conviction even if her inexperience does cause her to slip up regularly. A relationship forms with the protagonist being the unwilling Senpai to a Kouhai who wants him to sort his act out. This is a mutually beneficial kind use of the Kouhai archetype since it endears the player to both parties where their banging of heads humanises them. Only visual novels containing strongly defined protagonists tend to use this type of Kouhai given a self insert would not provide enough material to create a believable dynamic.
 

Conclusion

 
Age and seniority are the defining elements of the Senpai/Kouhai character where their relative position to the protagonist often defines their personalities and place within the world. This means a Senpai/Kouhai has to occupy a place within a social hierarchy like a school and assume the roles associated with their status such student council president or a new club member. It also results in the formation of certain archetypes to meet the player’s exceptions from the gentle and mature Senpai to the impulsive and emotional Kouhai. When they end up in a romantic relationship with the protagonist their role as a Senpai/Kouhai has to awkwardly fade into the background so the pair can be on equal ground and avoid any unfortunate abuses of power. Overall, the Senpai/Kouhai is born from the rigid and structured nature of Japanese society and it makes little sense to use it outside of this context so it is best avoided if you are not deliberately trying to emulate this style.
