Isao Shinomiya [The Unbreakable Iron Wall] is a 5★ Blunt Defender who is very good protecting allies through powerful shield-based defense. He stands out as one of the most reliable defensive units in the game, capable of anchoring teams in high-damage encounters.
His Combat Skill grants Shields to allies, allowing him to mitigate incoming damage before it is taken. While he does not provide HP recovery, his shielding is highly effective at preventing burst damage and maintaining team stability throughout prolonged fights.
Isao becomes stronger as his shields hold. Each time a shielded ally is attacked, his DEF increases, and his DEF is further boosted while he himself has a Shield. By maintaining shields instead of constantly reapplying them, Isao can create increasingly durable barriers that scale over time.
Beyond defense, Isao also contributes offensively. His Passive Skill grants a DMG Dealt buff to all allies, scaling with the number of teammates currently shielded. Keeping shields intact not only protects the team but also increases overall damage output. Additionally, his Combat Skill raises allies’ Effect RES, making him especially valuable against enemies that rely on debuffs or status effects.
