Considering the weirdoes Naoya attracted (like Loki), 'Al Saiduq' seemed somewhat okay, which was saying something as he was some strange box creature. Kazuya would have thought he'd've remembered meeting such a thing in his life, even as a child, but - whatever. Maybe this box was talking about Abel.

Kazuya still saw himself separate from Abel. He just...wasn't sure what to think about it, so settled for the mature way of dealing it by ignoring it completely. Perfect.

"How much space do you have in there?" Kazuya asked in amusement at the water pouring out of Al Saiduq's insides.
