Kirby is with the group at the moment.

Also, I should take this chance to remind everyone (but especially [@DracoLunaris]) how Strikers work. Bonding with a spirit to make it a Striker creates a relationship where its spirit is linked to your main character's for sustenance. Strikers have a set amount of effort they can expend, whether attacking, healing, or whatever, before they have to de-manifest. Just being manifested slowly drains this energy, but actingtakes more. In combat they're meant to act like assists in team-based fighting games, popping in for a moment for an attack, support action, or string of attacks before vanishing again to recuperate. If you're not familiar with assists, thinking of them as temporary summons might help. In a noncombat situation they can manifest for longer, but regardless they can't be around all the time. In exchange, they can't take permanent damage, instead simply de-manifesting if hurt too much.
