The 100 Girlfriends Who Really, Really, Really, Really, Really Love You - Chapter 8: Everyone's Favorite Swimsuit Chapter

I am the bone of my love  
Fluff is my body and purity is my blood  
I have created over a thousand girlfriends  
Unaware of bad ends,  
Nor aware of progress.  
Withstood pain to create flags, waiting for one’s arrival.  
I have no regrets. This is the only path.  
My whole life was Unlimited Girlfriend Works

Maybe a reverse trap tomboy lifeguard so that we get to see Nano and Hakari’s annoyance when they finally manage to bring a “male” staff member back to give MC CPR, only to realize they’ve just added another girlfriend

NTR guys try to intrude on MC’s territory.  
Fools they are, for MC is the Demon Lord of Romance, the crusher of men’s hopes, the modern-day Genghis Khan. What hope do they have? The school’s baseball star hides his girlfriend when MC walks down the hallway.
The fertility goddess from the next class over? You don’t need to be a farmer to know he’s tilling her fields.  
That twin-tailed cutie you just want to make laugh? She won’t even glance your way, but he gets to see her smile.  
The quiet girl in the library you were working up the courage to approach? Now her heroic fantasy novels have been replaced by the Kamasutra and Aleister Crowley’s “How to Enjoy an Orgy”.  
That cool genius beauty who caught your eye? Under the stairs, she’s efficiently using break time to suck him dry.  
Know him and despair, for God’s wrath has descended upon this town.
