"Character Development in my r*pe fantasy manga??"
Seems like it, and I forgot I even read this far two years ago lmao. Saino does seem like he's being let go too easily here, considering he brainwashed every single one of those girls there... and yes, creampied every one of them repeatedly while under the influence.
Maybe they somehow had an interest in Saino-kun since the beginning, making the escalation of their feelings much smoother. That, folks, is plot armor right there.
Though, after all the manipulation and s*xual assault, this series of events have been a huge relief. I'm glad Saino-kun has come clean with all the manipulation, decided to be genuine (especially with his bickering with Akitsu), and made an internal promise of making all 4 of them happy.
So his true goal has been exploring the dungeons, and all the brainwash r*pe is but a means to an end? Sweet. Now he's under the care of a tight-knit quartet, and he's got to take responsibility~
I'm glad for Sensei, she's still the guardian of a makeshift family despite it technically being an orgy of five. Props to Akitsu-san, as her innermost curiosity and love for Natsuno is intact (even unbreakable, perhaps). Good thing on Natsuno-san as well, since Saino-kun was her supposed crush before all this madness.
For Fuyushima-san though... I'm glad she's with Sensei in all the good s*x and dungeon shenanigans, but she needs some more love from Saino-kun. The Ice Queen has been snooping around Saino's immediate surroundings for the past few chapters. Can she read the tool descriptions? Did she see the group chat on Saino's phone? How does she feel now, having perhaps no say on his Fated Lover being shared between the four of them?
Ice Queen is cool asf. But even ice gets to melt sometimes, y'know?
