Kai

Kai is a hero from the planet Shiranai who finds himself facing the Viral army while trying to recover his memories while also confronting his former comrades from the Guardian Corps.

• His appearance is based on that of a ninja; he has a holographic scarf on his back
• She can't dance or write well
  A serious and level-headed fighter, Kai is a stalwart among the nine Guardians, known for his reliability. He is highly respected by the Guardian Corps and ordinary bots alike as a hero who fought against the Virus Army, so much so that he is addressed by his title until he requests otherwise. Despite his unpleasant appearance, it is suggested that he can maintain friendly relationships with ordinary bots, as seen in his playful interactions with KID alongside Bit.

Kai suffers from memory loss as a result of the damage he sustained during the first Virus Army Conflict. Although some of the other Circuits comment on the fact that he has changed in some way, this could be due to the fact that they have become Rogue Circuits and are simply exaggerating.
