Sanome Prince's side
|Debut||Chapter 2 (Volume 1)|
Koh is a talking sword snake. He has been with Narushige since the latter was a child.
Koh is an average-sized snake, unlike the big serpents that, upon death, turn into rivers. He has rainbow-colored scales. When not in sword form, he is usually found coiled on Narushige's shoulders.
Koh (虹) means rainbow.
Koh memorized a lot of words thanks to Rakan's electronic dictionary, but his word usage is a little weird. There are times when he complicates things when he engages in strange conversations with Chigusa.
- He can turn into a sword.
- As he himself is poisonous, he can grasp the composition of a plant's poison and its cure.
- He cannot use his sword form to cut his own species; he can't transform into a sword in front of serpents.
