Chachamaru ( (ちゃ) (ちゃ) (まる) Chachamaru?) is a feline familiar that assists in Tamayo's medical research with Demon blood.

Appearance

Chachamaru is a small, tricolor calico cat with black, white and brown spots. It has big amber eyes. On its back, it wears a brown box with a syringe created by Tamayo with the purpose of collecting demons' blood. Around its neck, it wears a necklace with a paper talisman that was made and given by Yushiro, which it uses to hide with Yushiro´s Blood Demon Art.

History

No information is given on the cat, it is simply introduced as Tamayo's familiar used as a transport mechanism for her medical studies. It can be presumed that it has been helping Tamayo and Yushiro for quite some time, as it is well-trained. Like many cats, Chachamaru likes pets, and will briefly stop for them before returning to its work.

Yushiro decided to demonize Chachamaru before the historical battle against Muzan, however no specific details are given regarding the process of its transformation. [1]

Synopsis

Drum House Arc

Although Chachamaru doesn't collect any blood during the battle against Gyokko and Hantengu, it is seen delivering a note written by Tamayo, seemingly to inform Tanjiro that there is a possibility that Nezuko is capable of overcoming the sunlight.[4]

Dimensional Infinity Fortress Arc

Chachamaru is seen during the battle with Muzan, after the Infinity Fortress collapses. The cat jumps above the remaining pillars in order to administer an antidote to stave off the poisonous effects of Muzan's attacks. As a result, it is sliced in half by the demon.
