Daishi Mamura (older brother)
Like his older brother, Daichi has light-colored hair that is a tad unkempt. Due to their similarities, he is referred to as "Mini-Mamura" by Suzume when she first sees him. Because of this, it can also be assumed he too has blond hair and red eyes.
Daichi is shown to be immature, having teased his older brother for having a "girlfriend" (referring to Suzume), although that is not unusual considering his age.
In Mamura's flashbacks, he was seen crying and stopping his mother from leaving their house.
- He, like his two brothers, has the character "dai" (大) in his first name.
- The animal in Daichi's name, horse (馬), is the "ma" in "Mamura." Though 馬 is normally read as "uma" when standalone, due to kanji having multiple readings, it is the "ma" in this case.
