A delusional brat is getting cocky, so let's use your fiancé to put her in her place!!
In this world, there are things called Demon Rings. They are rare items that every human covets.
At high school, Airi Momose became the fiancé of the demon Leon Astel and began using that status to boss everyone around.

From then on, she was sweet to the boys but harsh to the girls. Guest wanted to save the other girls from their suffering and stood up to Airi.

His electricity was incredibly painful and left a scar on one arm.
After school that day, while Guest was walking home alone, it suddenly started to rain. Triggered by the rain, the tears wouldn't stop. "I'm scared... I'm scared to go to school..." While crying alone in the rain without an umbrella for several minutes, Guest found a ring.

The ring slipped onto the ring finger on its own and wouldn't come off. Then, someone held an umbrella over Guest from behind.
