"You're a...a..." Kazuto struggled to find the correct word that described a leader of a family here. "A don?" he finally asked with some concern. Tsuna must either be stronger than he looks or naive. The other didn't even seem to have the foresight to ask which family he was in! Unless their family was an ally to the Mendolia, they were probably considered an enemy.

Which would be a pity, because Kazuto already liked Tsuna and didn't want to have to face him as an enemy someday.

"If you're a don then you shouldn't be without bodyguards," he continued worriedly.
