Setsuko

Setsuko is a 9 foot long saltwater crocodile. She has a lazy streak and a great fondness for music. She likes to sing; amongst her kind she is known for her musical talent. (Note: musical talent usually only evident if you are also a crocodillian. She bellows.)

Setsuko favors ambush when attacking, but she's not opposed to using her surprising speed to run down enemies, either. Or using her considerable size to intimidate. She's especially formidable in water.

Asahi is her first contractor, and she is its main summons. The pair are close friends even outside of the contract and spend plenty of time together, often playing duets. Setsuko contracted with Asahi after it saved and returned some of her mother's lost hatchlings -- something that impressed the crocodiles enough to earn Asahi their scroll.
