Listen, the Starlights’ names/titles don’t make any sense outside of maybe Star Fighter, so I’d like to think they’re loose translations from a language from Kinmoku.

Star Fighter is probably pretty in the nose, and I’d like to think Star Maker is like, technically correct, but it specifically refers to the creation of poems/stories/songs (Taiki is essentially a bard you can’t change my mind).

Star Healer is where it gets weird, because their name is actually a word that means something like “purification by fire” (hence their strictly offense powers, and their Serious Laser), and since there’s no way to succinctly capture that, whatever translation magic is present went with an approximation that is understandable but also way off
