Isao Shinomiya from his younger days joins Kaiju No. 8 THE GAME as an Attacker who can deal immense damage!
Experience the power of Isao Shinomiya in his prime — the man who made his name as the Captain of the Japan Defense Force’s First Division. As a compatible user of Numbers Weapon 2, and an expert of the Squadron-Style Combat Technique, every strike he delivered with his gauntlets possessed immense power.
In the game, his damage increases for each Kaiju on the field, accumulating Valor with every attack dealt to Kaiju. When Valor is at max stacks, he deals additional blunt damage after activating his Combat Skill or Ultimate Skill.
In stark contrast to the previously released ★5 [The Unbreakable Iron Wall] Isao Shinomiya, who debuted as a symbol of defense, this version of Isao is an Attacker who specializes in AoE moves, capable of turning the tide of battle.
The strongest fist in the Defense Force roars once again!
