Tsu is the Tinkerer of the crew and not so decent of a fighter. He is more then likely the least 'piratey' member of the crew. He is very knowledgeable on top of being very good with gadgets. He became a pirate as a result of the taking a deal with Scarlet, She'd raid an abandoned underground city for him, with him and he'd become a part of the crew, an adventure that benefited both of them. While he prefers not to drink alcohol, he's fine and happy with drinking 'fruity-drinks'. His addiction lies not with alcohol like scarlet but rather his insatiable gambling desire.

Oddities:
-I Can Fix It: Being a Tinkerer Prodigy essentially, he's incredibly good at reverse engineering as well as making and repairing gadgets.
-Life's A Gamble: A gambling man at it's finest; Scarlet's drinking habits are comparable to his gambling habits.
-Not Luck But Skill: For whatever reason, he seems to have some unnatural SKILL about things that happen, which certainly helps his gambling.
