Kaminari Weapons

A few days after Master Hayato's arrival, Dante had been attending his lessons with Alice out of curiosity.

He wasn't participating at first since he wanted the sword-master to focus on teaching Alice the basics before he could interrupt their lessons.

The warlock noted that Hayato was using blunt swords when sparring with Alice, and he hadn't unsheathed his katana a single time since arriving at the Jade Palace, not even when showing his student a few basic swings.

He also noted he hadn't seen the man's face as he was always wearing his tengu mask, but the warlock didn't care as much as seeing the sword.

After one session with Alice was finished, the warlock decided to inquire about the man's sword, saying that he felt something strange coming from it. However, it wasn't any type of magical energy—such as umbra or mana.

"Ah, you have a good eye!" Hayato said.

"This is a 'Kaminari Weapon,'" he continued.
