Spike

Spike is a human on Mutazione who runs Spike's Bar. He serves drinks and fostered Miu as she was growing up. He has an old crush on Claire that is painfully exposed during an ill-thought gesture from Miu, who played a love song he'd written in front of Claire without permission.

History
Spike arrived on Mutazione twenty five years before the start of the game. The boat he arrived on is called the Lolabye, which he says is in reference to someone (Lola) who broke his heart while he was naming it. He was still recovering from this heartbreak when he arrived.

His original plans had been to stock up on supplies and continue traveling, but ultimately he stayed. He tells Claire privately that her generosity was a key reason for this.

Spike is musical, playing guitar on stage with Miu and Tung, as well as writing songs. At some point he writes one about his love for Claire. He keeps his song on a tape on his boat, which Miu later steals to play.
