Takumi is a major playable character in Fire Emblem Fates on the Birthright and Revelation paths. He is the third oldest of the Hoshidan royal siblings, and has two retainers, Hinata and Oboro.
Takumi is the third child of four in the Hoshidan royal family, being the younger brother of Ryoma and Hinoka, the older brother of Sakura, and the son of Sumeragi and Ikona. In addition, he is the stepson of Mikoto, the stepbrother of the Avatar, and the adoptive brother of Azura. In order to gain recognition for his strength, he has been tirelessly perfecting his practice of martial arts. Although not explicitly stated, Takumi does have some skill with the blade, but when he was humiliatingly crushed by Ryoma during a sparring match many years prior to the events of Fates, he chose to become an archer instead.
At the end of Chapter 6, depending on the side the Avatar chooses, Takumi's involvement in the plot will be altered.
