[System + soul transmigration into Toyokawa Kiyotaka + girls' band + lighthearted and fun story] A viewer dissatisfied with the anime's story transmigrates into the most useless father of all: Toyokawa Kiyotaka. He could have wished for infinite money, cleared 16.8 billion in debt, and spent his life carefree with Sakiko. But he chooses the harder path: becoming Takamatsu Tomori's "lost big brother," Wakaba Mutsumi's "savior," Shiina Taki's "person who made a promise," and MyGO!!!!!'s manager. Because Tomori said, "Let's stay lost together for the rest of our lives." Because Mutsumi said, "I want a home too." Because Sakiko said, "Where you go, I'll go." This is a story about "becoming family": not through blood, but by choice.
