[Crossover] Touken Ranbu: The Warm God's Dark Honmaru

A young man with powerful spiritual energy accidentally falls into a space-time tunnel while fleeing from pursuing monsters, landing in a desolate Japanese-style courtyard.

How can this exceedingly gentle human boy heal the gods' hearts, wounded and scarred beyond repair?

And how will the fallen gods treat this pure human child, as innocent as a newborn fawn?

Teacher Cat: Ah! You bastards, let go! That's my prey!

The Swords: Go eat your steamed buns.

Natsume: [Smiles helplessly, then unleashes the Friendship Fist]

Worlds featured: Natsume's Book of Friends, Touken Ranbu, Onmyoji. Umm, let's start with these. I'll decide on others later.
