For a recent 30-Day Drawing Challenge theme, here's a reference for Takumi from "Eternal Storm".
Height: Between 5' and 5'3"
Residence: Japan A.R.E. (That stands for "Alternate-Reality Earth")
The son of the Key-Seekers' head, the Grand Seeker. He's sent with the Keyholders to act as a monitor.
Takumi is very detached and business-like due to the way he was raised. He's also very hung up on procedures and rules, earning him the nickname, "Mr. Protocal", from Atsuko. He shows little emotion around other people. He only lets his guard down with Shiri at first.
