Synopsis

A man called Jin Momoi finds a baby inside a peach-shaped capsule whom he names Taro and raises. 21 years later, mysterious monsters called the Hitotsuki begin appearing when humans overcome with their inner desires are taken over by spirits infused with powers related to the Super Sentai from the past. Taro, and four other individuals selected by Jin; Shinichi Saruhara, a smart but eccentric young man, Haruka Kito, a high schooler manga artist, Tsubasa Inuzuka, a wanted fugitive, and Tsuyoshi Kijino, an ordinary salaryman begin fighting the Hitotsuki and saving their hosts as the Donbrothers. They are later joined by Jiro Momotani, who was also found in a capsule as a baby and raised in a rural area, and aspires to become a hero.

Also standing in their way are the Noto, elusive and ruthless individuals from a higher plane who stop the Hitotsuki by sealing their hosts in another dimension, unlike the Donbrothers who use their powers to rescue them, and the Juto, strange and powerful creatures who are a threat to both humans and the Noto. The Donbrothers also count with the secret help of Kaito Goshikida, the owner of the coffee shop Donbura who transforms into Zenkaizer Black.
