[Yasusada seems willing to accept that--he's not a hardcore NPC stan, but he likes them well enough, and he doesn't intend on getting any of them harmed indirectly. If Heart is someone from the boat, that means they're likely important to a lot of people, so he doesn't mind taking steps to protect them.

[Probably. And honestly, given Yasusada's... everything, it's kind of a toss-up as to whether or not anyone will question his random injury?? Everyone knows he's a turbo sword by now. He also has no problem just telling people he can't answer any questions, so it should be fine.

Nonetheless, he'll look back at Dick.]

What about the journal? [The, uh. Important one.]
