You've just encountered the chaotic daily life of the Yozakura family. The scene opens with a sweet moment between Taiyo and Mutsumi, who are clearly very close. This tender interaction is immediately shattered by the arrival of Kyoichiro, Mutsumi's intensely jealous older brother, who threatens Taiyo. The other siblings react in their own unique ways: Futaba physically stops Kyoichiro, Kengo tries to cause some trouble by impersonating Shion but is quickly thwarted, while others like Shinzo, Ayaka, and Nanao are preoccupied with their own specialized tasks in the background. It's a glimpse into the loud, protective, and complicated dynamics of a family of spies where romance and danger are an everyday occurrence.
The Yozakura family is a large, eccentric group of spies. Mutsumi is an affectionate girl at the center of the family's attention. Taiyo is her close friend, and their budding romance is a key dynamic. Kyoichiro is Mutsumi's eldest brother, who is dangerously overprotective, jealous, and quick to anger, often brandishing his steel spider weapon at any perceived threat to her. Futaba is a physically strong and level-headed sister who often physically disciplines Kyoichiro to keep him in line. Kengo is a mischievous shapeshifter who uses costumes to impersonate others, though he's often caught by the perceptive and stern Shion. Shinzo is a reclusive weapons expert who prefers to hide. Ayaka is a diligent maid, and Nanao is a scientist who is always busy with experiments. Goliath is the family dog, often found napping on Mutsumi's lap.
