BOY HOWDY, this request is going to be one heck of a reach, but I figured I might as well ask it here. I only remember a scene from a single chapter, so I understand this ain't going to be an easy one.

Basically, it's a Non-H (surprisingly, given what I'm about to describe next) fantasy or science fiction adventure manga in which the protagonist is fighting some nude girl in a black void of sorts, and she's insanely powerful. He somehow gets the upper hand, and begins to grow before disappearing into nothingness. Only his voice can be heard, and the girl asks where he is, only for him to reply that he was preparing his "final attack".

He has apparently grown to the size of a planet. And his preparing of his attack was powering up a cannon.

Except it was not a cannon, it was

his dick.

He defeats her by

literally shooting an incomprehensible amount of cum at her. That is by far the most... "unique" fight scene that I read last year, by a long shot!!

I believe I found it initially by searching the

"bukkake" tag with the ! "Hentai" genre excluded, but I can't seem to find it again! If you can somehow recognize this manga from this scene alone, then you are a god and have my thanks. It's a series, and it was being translated in English by a fan translation group, but I'm at a complete loss when it comes to the title of this one. :'(

I do remember more about the scene, so I can definitely try to describe more, if necessary!

That would be chapter 14-15 of Makikomarete Isekai Teni suru Yatsu wa, Taitei Cheat...
