Neko is the second of The Ruin Walkers, and is blessed with an inexhaustible teleport ability. She can warp herself anywhere, anytime, with almost no consequences, as long as she has seen that place before. If not, she may end up inside a wall.
Despite having such a powerful ability, and being the second oldest of the Walkers, she is shy and insecure. For some reason, she has cat ears permanently affixed to her head, and nobody is really sure why. She is obsessed with all forms of anime. The only real "friends" she has are her siblings and Dr. Alphys.
