Welcome to Demon-School, Iruma-kun

Iruma is safely reunited with Lead. But apparently, Lead had the Vase of Endings he had successfully obtained stolen by Elizabetta. However, it appears as though the one who took the vase was not Elizabetta, but someone else. Lead uses his bloodline ability, Controller, that had been strengthened through Robin's training and tries to track Elizabetta down. What he ended up hearing were the voices of Elizabetta, Clara, and Keroli in a hot spring?!
