Chapter 8 of The! Beach Stars has been released.
Spoiler for Chapter 8:
Very interesting chapter. It starts out with the girl Kagurazaka going into a trance like state and beginning to super spike balls that are getting past Iruka and Hitomi. It turns out that the technique that Kagurazaka is using is similar to Hitomi's Mach tech she used back in the Beach Stars!! match. It gets more interesting that all of a sudden Iruka then starts to get into the zone and is having a spiking war with the other girl.
The match ends with the other team giving up after Kagurazaka's body gives out. It is also known that Iruka's main rival also passes on to the next round. During the chapter, it would seem that another rivalry is taking place.
