Mikado Aisaka/Future Nanashi

https://static.tvtropes.org/pmwiki/pub/images/1bitheart_mikado.png
Click here to see his second appearance (Major Spoiler) 

"Yes, I'm Mikado. That's probably extremely trivial information to you, so don't worry about remembering it."
Voiced by: Tousayu

Mikado is Nanashi's older cousin and the creator of the Master Program. He has been able to maintain a healthy website ever since its creation. However, he soon discovers hackers getting into the system.


  • Assimilation Plot: He meant to unify the world and establish world peace. However, he was going to accomplish this by using one mind.
  • Big Bad: He’s the one behind the hackers.
  • Big Brother Instinct: He's allowed Nanashi to stay in his apartment ever since he stopped going to school. He even designed his BitPhone to look the way he wanted it. Subverted as he's the adult version of Nanashi.
  • Bishie Sparkles: It's kind of hard to see them, but they are there near his head.
  • Bunny-Ears Lawyer: He's cheerful and goofy, but also the creator of the Master Program.
    • Misane reveals that Mikado isn't the original developer. It's also revealed that he's a part of the Hackers.
  • Death Seeker: In light of his impending Power Degeneration, he decided to spend the rest of his life to create world peace... But he knew that the past Nanashi would likely oppose him, and even if he did succeed, he'd wipe himself out of existence in the process. Should Nanashi choose to kill him, as he does in the Bad ending (or in the Normal ending, by killing himself), he accepts it calmly.
  • Foreshadowing: According to his Mutter info, he's eight years older than Nanashi and Misane says he's from 2230 (eight years from the current time period). Coincidence?
  • Graceful Loser: In the Good Ending, when Nanashi rejects his plan and grows past him.

  • Heroic Albino: His true appearance. However, the heroic part is a bit of a grey area.

  • Ret Gone: The Extra Chapter reveals that he vanishes from the time machine while returning to the future.
  • Self-Deprecation: He doesn't like other people being called idiots, but he's fine with being called an idiot himself. Since he's the adult version of Nanashi, his self-esteem is extremely low.
  • Stepford Smiler: He's a much stronger version of Nanashi since he never made friends in his timeline.
  • Treacherous Advisor: He's the leader of the Hackers and Nanashi has been going to him for help throughout most of the game. He's not that treacherous either, but he shouldn't be trusted.
  • Walking Spoiler: He's a part of the Hackers and he's from the future.
    • He's also Future Nanashi, which officially explains why Misane wants the current Nanashi to make a lot of friends.
  • White Hair, Black Heart: In his Nanashi form.
  • Well-Intentioned Extremist: He instigates an Assimilation Plot to prevent a Bad Future he came from.
  • Woobie, Destroyer of Worlds: While his goals don't involve hurting anyone, he did mean to bring world peace through forceful measures.

But then she uses a mishmash of letters and symbols in one sidequest conversation and in her Mutter messages. The symbols can be barely made out to be intelligible Japanese, but it's likely a visual interpretation of heavily slurred speech.

  • It Amused Me: He keeps saying that he's amused and interested in what Nanashi has to say. He's even interested in the Hackers.

  • The Stoic: Her current piece of art shows her wearing a vapid expression.
  • The Un-Smile: She gives a small one to Nanashi, which creeps him out.
  • Yandere: Once she and Nanashi start "dating", she becomes overly attached, jealous of anyone Nanashi may be spending time with that isn't her, and is willing to kill anyone she perceives as a threat to her relationship with Nanashi.
