[Harumasa debates with himself whether or not to let his siblings know about Luke. However... he's kept so much from them for so long that it feels... wrong to keep this from them, too. And he already feels like a monster for lying to Luke's face about not knowing him. So, he steels himself and makes a call to his siblings.]

Heeeeyyyy, so... funny story. That Luke guy on the app that just started complaining about the tree? That's, uh... that's the same Luke we know. If you guys remember him. He was that shy little kid who liked to hide behind me?

But, uh, there's a problem. He doesn't remember anything from that time.
