In the GUTS Team of the Tiga World, I Turned Melba into a Girl from the Start

[Ultraman fan fiction + monster girls + collectible encyclopedia and training + pinup girls + gap moe] Su Yu transmigrates into the world of Tiga and becomes the youngest special biological consultant at TPC. He also awakens the [Monster Girl Containment Encyclopedia]: as long as he defeats a monster to the brink of death, he can forcibly transform her into a girl, forge a master-servant contract, and contain her permanently! While Daigo is still hard at work practicing beam techniques, Su Yu has already turned Golza into a sultry mature beauty, Melba into a tsundere with twin tails, and even the world-destroying evil god Gatanothor into a teary-eyed, tentacled, white-haired loli. But transforming monsters into girls comes at a price: the higher the encyclopedia’s level, the stronger the backlash from containment, and every forced contract tears at the balance of light and darkness within his body. When Camilla discovers that the dark army she worked so hard to build has all become someone else’s maids, when Hui finally pries open the door to the “girls’ dorm” and finds it full of monster girls, and when Keigo Masaki raises the Dark Spark to crush everything with his power, Su Yu simply flips open the encyclopedia and smiles meaningfully: “Come on, let me show you what a true full-encyclopedia lineup of long-legged beauties looks like.” A hundred chapters later, Su Yu looks up at the stars. “I heard the Land of Light has an Ultra Fly? ...What kind of girl would that thing turn into?”
