Tsugumomo Wiki

Suou Sumeragi (皇 すおう, Sumeragi Suou) was the elder brother of Sunao Sumeragi and previous owner of Kotetsu.


Suou was a young man with short hair.


Suou was a kind and caring individual who treated Kotetsu well and worked diligently so his younger sister could live an ordinary life.


Suou worked as the exorcist for Komiya where he was appointed by Honoka and partnered with Kotetsu. Suou often spoke about working as an exorcist to achieve an ordinary life for his sister and often spoke appraisal of Kotetsu to her.

Suou was killed by an amasogi, prompting Sunao to seek revenge while blaming Kotetsu for failing her brother.
