A new boss spawns every
6 hours — a real anime character pulled from MAL weighted by popularity. Deploy
5 characters and deal as much damage as possible in
60 turns.
The boss scales to your
collection strength — the stronger your roster, the harder the boss that spawns next rotation. This means progression genuinely matters: pulling stronger characters makes future bosses tougher, but lets you hit higher loot tiers. You can't game it by deploying weak characters — it always measures your whole collection. Average teams need all
3 attempts; strong geared teams can clear in
1–2. The boss hits
hard: it AoEs all 5 characters every turn and has 3 phases — gaining more ATK and speed, then applying a team-wide DEF Down at 33% HP.
The boss has
12 loot tiers — deal more cumulative damage (across all 3 attempts) to unlock better rewards. Early tiers give R/SR Chests; late tiers give SSR Chests, Crystals, and UR Shards. Defeating the boss gives
500+ crystals (scales with difficulty) and a
50% chance to capture the boss character as SSR or UR — the capture plays out as a full summon reveal, just like pulling from the gacha.
Attempts: 1st is free, 2nd and 3rd cost 100

each. Damage carries over between attempts.
