The security guards Kang and Kong attempt to remove the boys as the Hero Lab's existence is a secret, but Great Saiyaman 3 tells them to let the boys go as they seem to have a reason for wanting to be there. The boys ask if they've seen Nim though they have no idea who he is. Bocacchi thinks some happened to Nim. Beat assumes another anomaly is involved with Nim's disappearance but stops himself from revealing to much and says the world hasn't been safe lately and Note adds to Beat's cover story of rampaging cosplayers to explain away the recent incursions by game world enemies into their reality such as Cooler, Dabura, Spopovich, and Yamu. Beat is certain it is definitely the work of a game character but decides its better to feign ignorance to prevent creating a panic among the Town's civilian population. Yuto reveals that in addition to Nim, more kids have gone missing. Yuto also reveals Nim hasn't been home in ages and his mother is worried sick. Bocacchi says though Nim likes to go out he always comes back home and it is unlike him not to.

He asks Beat, Note, and Froze if he can count on them and they all agree. Beat suggests they hit the Hero Stadium first, while Great Saiyaman 3 covers the town and to let him know if they find something.

Froze says staying where they are would just be a waste of time and Beat agrees saying they should report back. He contacts Great Saiyaman 3 and he asks if they found anything and Beat is about to tell him when Note points out another tear in space like the one Dabura, Yamu, and Spopovich flee through previously. Froze has never seen one and asks what it is. Beat says he wishes he could tell him but before he can finishing explaining why he can't he notices they are being sucked in.
