Kakegurui x Ayanokouji

Atsuomi provided Ayanokouji with a year on ANHS.

So during Y1V7, he contracted Ayanokouji that he'll not interfere with Ayanokouji staying outside the White Room in exchange of him transferring to Hyakkaou Private Academy at the start of his second year, in order for him to raise his influence and gather more funds for the White Room.

So, Ayanokouji has peaceful Winter vacation though not completely with Ryueen, but yeah, he spend more days with Ayanokouji Group, Sakayanagi, Karuizawa, Shiina, Ichinose, etc.

Then he met Jabami Yumeko
