23-4 BROKEN MASK
23-4 Broken Mask is the 4th stage of 23 — Dead End Night. Previous stage: 23-3 Dark Premonition. Next stage: 23-5 Agape's Cage.
Sunfish Jones is Angel. Anti-Angel units take less damage and deal more.
Sunfish Jones reaches 840 range. Units that out-range it can chip safely without taking hits.
Sunfish Jones has a deep HP pool (1,200,000+ even before stage magnification). Heavy single-target burst shortens the fight.
BAHAMUT CAT S Huge multi-hit burst — a story-unlock powerhouse that deletes tanky enemies. 
KASA JIZO S Its castle forms hit for enormous area damage to crack Dark/Angel bosses. Also fits “Counter Angel.” 
GAIA THE CREATOR S Long-Distance multi-hit with Insane Damage — a generalist wall-cracker. 
CRAZED MONEKO A Big crit burst against tanky/Metal targets. 
KALISA S Big Massive-Damage Area hits. Also fits “Counter Angel.” All-Angel stage. Artist Cat or ULTRA SOULS ubers carry. Sunfish Jones boss appears at 99% base HP — his extreme range is the real threat.
All-Angel stage with Sunfish Jones as 99%-HP boss. Sunfish Jones has 1,500 range Long Distance — he outranges everything you can field. Community fix: delete his support (Heavenly Hippoe + Angelic Gory) fast with Artist Cat or Sanzo Cat or Holy Valkyrie burst, then either rush base or use A. Bahamut to bait knockbacks. Common failure: ignoring Sunfish's range and trying to grind through. He will one-shot your front line before you reach him.
