Imitation Nichirin Katanas
Katana
Hoshimi Lupin's dual katanas are made to imitate those of Shinazugawa Sanemi from the manga Demon Slayer, Hoshi's favourite series. They made them out of scrounged up metal and followed various tutorials to figure out how to craft them. They're quite good for a novice sword-maker. However, it's a talent they'd like to improve upon.
There are no magical effects imbued in the blade itself but with Isolde's lightning-manipulating abilities, they can combine those attacks to make something rather fierce.
These blades were a beta-test in order to analyze their current skill. Hoshi has intentions to make a new, better version.
