Three years have passed since Yurina's Union won the Vartok Fehda and the encounter with Tia and Selphie.

The protagonist, Konoe Akito, who became romantically involved with Silveria, accompanied her as her squire on official duties outside the academy. In the days spent supporting her and traveling from Fehda to Fehda across various regions, they came to understand each other better, strengthened their bond, and developed a deep relationship as lovers.

After three years, one day, he received a message asking him to return to the academy after a long absence.

When he returned to the academy, it was as lively as ever, with a slightly nostalgic atmosphere, and overflowing with bunny girls he'd never seen before?!

Tuari Fehda, the ranking tournament for new knight candidates held at the academy, left the academy filled with bunny girls due to its rules. Silveria and Akito, dragged into the Fehda by Stella's scheming, found themselves caught up in the turmoil alongside the other Unionism heroines, who all ended up wearing bunny suits!

This is an afterstory that takes place after Silveria and Akito became lovers, featuring a lighter tone, plenty of bunny girls, and more intense naughty content...
