Isao Shinomiya [Prime Fist] is a 5★ Blunt Attacker who specializes in AoE combat and excels in battles against multiple enemies. With AoE Combat Skills, Ultimate, and Follow-Up attacks, he is particularly effective in stages filled with groups of smaller Kaiju.
Isao’s damage scales with enemy count. He gains increased DMG dealt for each Kaiju on the field, allowing him to output significantly higher damage in multi-target encounters. This makes him a standout choice for content such as Large Conquest, where enemy numbers are consistently high.
His kit revolves around the Valor mechanic, which stacks up to five times by attacking Kaiju or at the start of his turn. At maximum Valor, Isao can trigger Additional Blunt DMG after using his Combat Skill or Ultimate, consuming all Valor to gain a CRIT Rate boost.
With three or more Valor stacks, Isao further enhances his damage by increasing CRIT DMG, scaling DMG dealt based on the number of enemies, and boosting the Additional Blunt DMG multiplier through his Ultimate. These layered buffs allow him to maintain strong, consistent AoE damage throughout extended fights.
