I am that male friend in the harem story - Chapter 17: Let’s sing a song!

Zach was a sci-fi game enthusiast who unintentionally crossed over to a magical isekai. Fortunately, he had access to the previous game system and could fight the magic-savvy aborigines with high-tech weapons.

“What the hell happened? Is my sperm capable of upgrading girls? Can my blood cause those girls to burst out instantly?”

He appeared to be having a fantastic journey.

Okay, maybe I can understand that. But a 'Chainsaw Demon'? What the heck is that? And where did you even pull this 'Sukuna' from?!When the Summit War kicks off, Sengoku and the Three Admirals stare at Reiner, who is sitting calmly upon the execution platform.'What?
