Taiko Kumo (曇 大湖, Kumo Taiko) is a character of the Donten ni Warau series. He was married to Koyuki Kumo and fathered Tenka, Soramaru, and Chuutarou. Taiko was the instructor of the Yamainu Squad. He suspected that the Fuuma clan was secretly working undercover.
Eleven years before the series began, Taiko and his wife, Koyuki , were assassinated by a masked Fuuma.
Taiko was caring and quite straightforward. He was also patient and an energetic leader to the Yamainu Squad. However, Taiko was also very strict whenever he thought it was suitable.
Taiko and Koyuki had a loving relationship. They openly expressed their appreciation and care for each other through amiable arguments that would end in hugs and verbal declarations of love. These declarations of love almost appeared to be heated arguments.
Taiko and Mutsuki had a comfortable relationship that resembled a parent and child's. For instance, Taiko would ask Mutsuki about his whereabouts, while the Ashiya family would not care.
