Shingo Mido

Mido keeps his light-brown hair short, swept toward the right, and perches a slim pair of black-framed glasses on his nose. His business attire runs to a dark suit paired with a white shirt and white tie. Misa Amane once remarks that he bears a likeness to Light Yagami.

Within Yotsuba, Mido carries two weighty titles, serving as a vice president over corporate strategy while also heading the company's financial planning, an arrangement made ironic by the fact that he privately dislikes finance. He earned a law degree at To-Oh University, lists fencing among his hobbies, and is the son of Eigo Mido, who holds a seat in the House of Councilors. Kira's methods turn his stomach, and he attends the group's lethal meetings against his conscience, mulling an exit even while clinging to a measure of loyalty toward the firm.

Mido is a fixture at the deadly Yotsuba meetings held among the eight executives. Suguru Shimura, no longer able to stomach the arrangement, approaches him, and on the night Higuchi is taken into custody the two convene quietly at Mido's home, where Reiji Namikawa joins them to weigh who Kira might be and how to stop him. Higuchi's capture that same night renders their plotting moot, and they never act on it. Roughly five months after L dies, Light wipes out the surviving Yotsuba members, Mido among them; the anime shows him mid-conversation with Masahiko Kida when a heart attack drops him to the floor. The television drama trims him down to almost nothing, granting him a single spoken word and letting him live, while the Relight retelling sends him plunging to his death from a tall building.
