The Murder Case That Is Too Impossible
Iaian is invited along with the S-Class heroes to a hot spring resort, after the Dark Matter Thieves failed invasion. While enjoying himself at the hot spring, he isn't satisfied that some of the heroes that did not participate in the battle were invited to the resort, but Bang manages to calm down the situation. The next day after the ceremony, the heroes find Zombieman murdered, stabbed in the back by Atomic Samurai's katana.

As Child Emperor interrogates every hero, Iaian is one of many alibis for Atomic Samurai so all suspicions are dropped. While the investigation isn't progressing, Tatsumaki tries to restrain everyone, until Zombieman suddenly wakes up. Zombieman later reveals that Atomic Samurai's katana was floating with green light surrounding it similar to Tatsumaki's psychic power when it stabbed him. Zombieman doesn't care about what happened the night prior and the heroes disbands.

Going Fishing with Middle-aged Men
Bang asks Atomic Samurai how Iaian is dealing with the loss of his arm at the hands of Melzargard, and Atomic responds by saying that Iaian is strong, and has already started training to get adapted to fighting with just one arm.
