Oh! I thought otherwise. But in that case I have an idea for weapons: How about weaponized toys from the 1880's? My first thought was jacks that doubled as bombs or shurikens... They're gonna be ranged since Kokichi is not used to things like boss fights IRL. Plus it suits someone who likes to pull strings and push buttons at the same time.

I can see Kokichi trying to bullshit his way out of being on a farm. He is not going to admit he has a sudden fear of them unless you manage to back him into a corner.
