After the Danger Room nearly killed everyone, Wolverine has taken it upon himself to teach the kids how to fight. Meaning, they fight him. But while the X-Men attempt to get on with their lives, the Hellfire Club has resurfaced and have revealed themselves as the people behind the incident in Genosha. They've begun to set in motion a plan to do something that isn't entirely clear at this point, starting with Emma's part to tear the X-Men apart.
The Japanese exchange between Hisako and Wolverine is translated as such:
Hisako: It's a shame that they admitted a murderous gorilla as a teacher isn't it...?
Wolverine: Don't you think it's shameful to your ancestors that you're always complaining?
