Tiga: The Monster Girls I Raise Are Seriously Fierce!

[Transmigrate + Monster Girls + Comedy + System] When college student Xia Yan was playing a knockoff monster-raising mobile game, his phone exploded and he transmigrated to the world of Tiga. He became an ordinary aquarium keeper and discovered that the mobile game had turned into his golden finger: [Monster Girl Ranch]. He could capture young monsters from this world or collect their genetic information, then raise and evolve them on his ranch, even turning them into adorable girls with monster abilities.

Xia Yan spends his days slacking off at the aquarium while raising all kinds of monster girls in his portable ranch. Golza becomes a tsundere earth-type loli, Melba is an energetic flying-type girl, and the Kyrieloids are somewhat yandere older-sister types... He has to feed them energy ores, train them through battles, and interact with them to raise their levels and affection.

When a monster appears in the city and Tiga is struggling to fight it, Xia Yan secretly sends out his own monster girls. To everyone else, it looks like monsters fighting monsters. Only Xia Yan knows that his girls are getting some “field experience.” His monster girls retain not only their original powers, but also human intelligence and a wide range of tactics. Gradually, TPC discovers that a mysterious “third monster faction” seems to have appeared on Earth. They often help humanity, but no one knows where they came from. As the master of these mysterious monster girls, Xia Yan enjoys his laid-back life of “raising daughters” and gets caught up in a daily comedy of wits and daring with Rena, Megumi Munakata, and the others who come to investigate.
