Saitama isn't doing too badly: What a luxury property is hidden beneath his apartment! Plenty of space, running water, just a little dark. Of course, it doesn't take long for him to get lost in the expansive corridors. And the monsters he crushes one after another don't lead him to the exit either. It's only when he encounters S-Class hero Flashy-Flash, also known as Ponytail, that a light bulb goes off for him. The bald guy annoys him so much that he zooms away like a speeding light bulb – and Saitama follows right behind.
