My 2D Waifu Transmigrated to My House

My anime waifus transmigrated into my home!

Shipgirls! Heroic Spirits! Valkyries! Card spirits...

Zero Degree is a powerful figure who used to be a Pokémon trainer, a Chosen Child, a commander, an admiral, a captain, a Master, and many other things.

He inherited every role and all his waifus from the game, and now his former waifus have suddenly transmigrated into his world...

What do I do?! Help, I'm waiting online!
