For Kotori Yusaki, the cutest person in the world is her brother Nakahara Chuuya, but his brother disappeared when she was three years old.
Although his brother is missing, Xiaotiao Yuzaoji will never give up.
At the age of six, Kotori Yu entered Academy City at an early age.
At the age of ten, she obtained her brother's information.
At the age of fourteen, Kotori Yu left Academy City and went to Yokohama through social practice.
Of course, flipping over a few bento boxes is just a piece of cake for Little Bird Yu Zaoji.
What's this?
The bomb disposal team where my cousin is? Save it.
Unlucky astral body? Save it.
Brother's friend? Save it.
A redheaded killer? Save it.
(There is a 3-year age difference between Private Design Zhongye and Zaoji. Xiaoniao You Zaoji takes her mother's surname.)
Intention: May all good things happen at the right time
