This list is based purely from my own opinion thus it will change from time to time as I unlock more characters.
Things to Note
- After the tutorial, you will be given a free 10x summon where you can re-draw up to 30 times. You are guaranteed only 1 SSR character every draw.
- Due to the nature of the game, you will need a mix of characters from the N rarity all the way to the SSR rarity. It is difficult for you to bring a full party of SSR characters especially in the early game as SSR characters tend to have high summoning cost.
- Characters that I have not obtain are graded based on Japanese wiki and reading of skill description. Will update once I get to use them.
