Biography
Episode 4:

When the group of hybrids travel into the decrepit, messy town allegedly named "Peron 6" (as a sign displayed in one scene would suggest), Yuki quickly teleports in front of Isa, and steals her purse. Isa decides to run after them where she later encounters them in a dead end alleyway. Yuki is temporarily unable to teleport and they are rendered unable to escape, since they had apparently "used up their power limit", as Isa says. Isa distracts Yuki and takes the purse back from them using telekinesis. After doing so and running off, Yuki regains their abilities and quickly teleports in front of Isa to block her.

After entering a leopard-like state, they harshly threaten Isa until the rest of the hybrids show up to get them to "pick on someone their own size". Isa manages to pacify Yuki and when asked their name, Yuki asks to be called as such. When asked to join the group, they quickly accept and is first given the food that they requested.

Andrew admires and is completely blown away by Yuki's speed when it comes to consumption, going as far as to ask Yuki if they could teach him to eat as fast as they do. Considering the fact that Andrew has many ties to speed, this may be a signal of a coming friendship or some sort of bond that will form between the two.
