Hiro notices a rather Ikusaba looking shadow cornering Saiyaka, he grabs a nearby pipe on the wall, grabs it and rushes over to protect Saiyaka. He says to ikusaba 'yo! chill out, dudette! Hina and Sakura died to protect Saiyaka, and both Celeste and Kyoko battled someone and won to do so. So I'm gonna have to ask you to back off or you'll get a head full of pipe!' She refuses to back off, resulting in Hiro clocking her and Saiyaka making it to episode 6.
Hiro approaches Kiyotaka Ishimaru and says 'it's your turn, dude! make sure no one kills Saiyaka ok?'
Taka agrees 'very well'
meanwhile, Junko Enoshima is getting rather angry she seethes 'how hard is it to kill a famous singer to bring despair to the ultimate hope? guess I'll have to do it myself!'
Taka explains the situation to mondo. Mondo replies 'you don't gotta do that, Let me handle this. If anyone tries to kill Saiyaka, I'll crush their damn head in!' see ya in the grand finale
