Masakuni Mido

Masakuni Mido is the Prime Minister of the Seito state of Japan and one of the five main antagonists of Kamen Rider Build alongside Night Rogue, Blood Stalk, Yoshiko Tajimi and Juzaburo Namba.

Like Yoshiko Tajimi, Mido seeks to dominate the entirety of Japan. However, unlike her, Mido is much more patient, willing to wait for the other nations to be weakened before choosing to strike.
