Phoenix Ikki. And I don't really have any suggestions other than ask the store if there's anything generic enough. A lot of us have some type of magic or power that would cause you trouble if we become enemies, but they are too varied and different to make it easy to just pick something and be well protected.

[It's not a threat, of course. Ikki has no interest or intention of making enemies with this guy, but no one knows the future and if for whatever reason Ace makes enemies with this guy's crew or the guy himself... Ikki will fight. Warning him and suggesting him to find ways to protect himself is as much kindness as Ikki will spare about this based on their shared circumstances of being trapped here.]

Though maybe you will be able to get something if you focus on something that can protect you from a physical attack and something for mental attacks.
