Yes, Boss. They were about to take another step. But suddenly, a flash of blinding light erupted. What is this?! Amidst the confusion, the scenery begins to change. Thud. Japapa, Noa, Tattsun, Yuan, and Naokiri seem to have been transported into a living room somewhere.

I have to protect them. That was what Japapa and the others felt in that moment.
