Motochika Chōsokabe is the twentieth leader of the Chōsokabe clan. He is best known in history for conquering the entire Shikoku island with his own resources. Motochika is often praised as the most capable daimyo of the entire island. Nobunaga historically disfavored him and mocked his reputation by calling him "the bat who refuses to fly away from its home" (鳥無き里の蝙蝠, torinaki sato no kōmori). As a reference to this, Motochika's nickname is "Bat" (蝙蝠, kōmori) in the games. His successor is Morichika and his concubine is Koshōshō.
