Weapon

When one thinks of weapons, one would probably think of firearms, blades, explosives, etc. One might even think of a hammer and a baseball bat. His card gun wasn't exactly a lethal weapon, but it was recognised as such, as were his smoke bombs and flash grenades. Before he met and began to watch (not stalking) a certain little devil, he wouldn't have thought of other everyday objects (besides Aoko's magical mop of course) being used as weapons. As a tool or a distraction, sure, but not as a weapon. He knew that one could use anything as a weapon (like a mop), but he never really thought about it before. He wasn't a particularly violent person, after all. First of all, he learned to fear footballs. Those evil, hellish, and round projectiles were dangerous (and sometimes life saving, but only sometimes though). Then he learned that anything durable could turn into a dangerous projectile when a certain someone tried to kick it at his head or any other part of his body. The most notable objects that were hurtled at him were fallen debris in burning buildings. Not that he was complaining as they often weren't actually aimed at him and served a different purpose. That, though, however, didn't make it any less intimidating. On the contrary, it was quite terrifying to imagine the force which made walls crack aimed at him. He suspected that the little demon had sometimes turned down the power of his shoes a bit and sometimes missed purposefully, but it was still disconcerting. Others—especially murderers—got creative with weapons around that death magnet, too; piano strings were just one of the innocent objects that were abused as a weapon.

After getting to know his true rival, he realised that literally anything can be a weapon, even an innocent roll of toilet paper or a bottle of water.
