The World Has Become a Game, and I Can Create Anime Heroines

Lin Meng was born into another world and lived out a second life. But in this life, just as he awakened the memories of his previous one, the world was gamified by an unknown entity. After changing classes, however, Lin Meng discovered that his class let him design the appearance and bodies of his summons himself. Does that mean I can handcraft anime waifus? And then even more surprising things happened! What? Because I've lived two lives, I can change classes twice? What? My summons' stats are linked to my mental stats? What? I have two classes, so I get two sets of stats when I level up? Then, from now on, my waifus are invincible, aren't they!!! Huh? My newly summoned waifus don't have souls, so I have to possess and control them myself? Fine! It's just one soul in two bodies, one soul in three bodies. I'll put up with it and be a girl for a while! But I smell so good as a girl~ Let me kiss you, hug you, and lift you up~ Let me have some fun~ (PS: A feel-good harem story. The protagonist and his waifus are invincible and never take a loss. He'll create a guild.) (A revival of old favorites: the once-popular heroines Asuna, Sakurajima Mai, Kasugano Sora, Gasai Yuno, and more.) (To be clear, the heroines are made by the protagonist. They only look similar to the originals and are blank slates with no memories.)
