Kasumi Mikumo

"These reporters... All deserve to be beaten with a stick."

- Kasumi Mikumo

Kasumi Mikumo (三雲 香澄) is a character in the manga and anime series World Trigger. She's the mother of Osamu Mikumo.

History
Through many passionate attacks in University, she managed to marry her current husband on graduation. The Mikumo family is a standard nuclear family; her son participating in rank battles at Border, her husband builds bridges overseas, and she does the laundry at the riverside. Doing so led to the discovery of a convenient stick being washed down the river.

Appearance
Kasumi is quite pretty and looks young for her age, with people believing that she is Osamu's older sister, like Karasawa. She has shoulder-length black hair and a fringe reminiscent of Osamu's.

Personality
Kasumi is quite concerned about her son and his life. When he was being barraged by the media, she expressed a desire to beat them with a stick. Additionally, when Osamu woke up in the ICU, the first thing she asked him was whether he and Chika weren't getting along well. However, she is understanding; as seen when she allowed Osamu to stay in Border despite the fact that he nearly died, stating that it was his life.

According to Ashihara Sensei's comment, she looks cool but is in fact a close-range attacker mother of one.
