In addition, many of his quotes upon seeing Yan-chan doing something unsavory have him react with shell-shocked horror. Cowardly Lion: Senpai has a variant of the "Loner" persona, meaning his reaction to seeing a dead body is to run off campus to call the police.Covert Pervert: When someone asked whether he'd really accept the Nurse's feelings on Twitter, the Dev replied by basically implying that he might have a nurse fetish.Cool Shades: You can give him a pair when you're customizing him.Sure enough, in the redesigned school (where the students finally sit at their desks), that's where his desk is. Conveniently Seated: YandereDev jokes that he has "the main character chair" seated in the back next to the window.That said, unless Hanako's surname gets programmed to change to whatever is set as Senpai's surname, the Yamada surname will be consistent despite renames. Canon Name: While YanDev stated at one point that he'd like players to be able to change Senpai's name, the character bio on the official site states that the male and female variants are canonically "Taro Yamada" and "Taeko Yamada" respectively.YanDev has said that Senpai will never join any club during the course of the game, though he'll drop in on several. Early in development, fans who delved into the game files discovered he was in the Gardening Club, as it was the original "null" club stat.He can also be seen on the school's Fakebook page asking about the age of the cherry trees on the main path to the front gate in old debug builds before it was changed to Sakyu who asked the question. Indeed, YandereDev has stated that if none of the rivals or Yan-chan existed, he would probably end up with the President of the Gardening Club. His interactions with Osana seem to confirm that he enjoys spending time in nature. The information Info-chan gives you on Senpai is rudimentary at best, but he is known to enjoy spending time outdoors in Akademi's courtyard.Heaven help you if he finds out that you killed his best friend and his little sister when he has low sanity It's been confirmed that just how much damage you do to his loved ones will affect the kind of ending you get, possibly including his committing suicide. Witnessing his best friend and sister die in front of while he is helpless to do anything will be the most damaging experience to his sanity. Finding a corpse will hurt it more, and finding out his best friend and/or sister are dead will damage it significantly. note Bloody weapons and pools of blood will damage it slightly. It will be damaged if he witnesses something disturbing. Broken Bird: Like Yan-chan, Senpai has a sanity meter.Even if rivals are dealt with non-violently, it appears he'll either suffer trust or abandonment issues, depending on the methods used. Break the Cutie: He has close relationships with two of the rivals ( Osana Najimi and his younger sister), and the developer has stated that the way they disappear from his life may give him serious mental problems by the end of the game, including PTSD.He has black hair by default and is frequently seen reading a book at the fountain during the morning, implying that he's a bit of a bookworm, but if Info-chan's comments in the Student Info are anything to go by, his grades (like everything else about him) are average. Blessed with Suck: He has the ability to instantly attract a harem of girls who all want to be with him.At first only the most average girls will like him, but each subsequent rival is more popular, important, strong, or otherwise difficult to defeat than the previous one. Big Brother Instinct: It's implied that he will have this to his little sister once she's implemented in the game.Beware the Nice Ones: YandereDev states if he's pushed too far and he finds out that Yan-chan was the cause of all his torment, it doesn't end well as we see Senpai grab a knife.Berserk Button: He finds people who commit crimes while wearing masks to be especially cowardly, and will attempt to rip your mask off if you kill someone in front of him wearing a mask, even at the expense of his own safety.Bald of Awesome: One of the hairstyles you can give him on the customization screen.Author Avatar: In Fall 2015, became one of YandereDev for a while (replacing Ayano), until Dev got his own unique avatar that looked somewhat different from Senpai several months later.He ( or she, eventually) is around 18 years old, has a "Loner" personality, and is in Class 3-2. Senpai is a regular senior-year student at Akademi High who inadvertently becomes the target of affection for Ayano-chan and nine other females at the school note (his little sister Hanako, while still a rival, has a completely different motive).
