Kasumi Mikumo

"Remember when you had brought the prospective enlistment documents about half a year ago, and how I was so opposed to it? When I heard you were severely wounded, I thought, "I told you so." But it's strange. Despite seeing that you were unconscious and wounded, not a single visitor recommended that you leave Border. I wondered why, but after today, I understood a little. Ever since you joined Border, you seem like you found what you must do. So do as you wish. It's your life after all."

- Kasumi Mikumo to Osamu in Osamu Mikumo 11.

Kasumi Mikumo is a character in the manga and anime series World Trigger. She is the mother of Osamu Mikumo.

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 thick 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. Most of the time, she has a emotionless mysterious face.

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.
