[{(no photo to show so,it is a random photo not the photo of the mc)}]
One day,the demon king of a alternative dimension was destoried with the whole dimension.He somehow revied in another dimension with a new body.The dimension he was revied had unbeliveable things.The whole world work in mana,every plants and non-living beings had mana.This dimension also had know that was not gainable in his dimension.He became curious and made a desigion to stay here and study.The demon got a new named sunpo maou.It was a name that fits perfectly.Maou slowly learned adapt in the environment and was now able to use some of his ability.

After 25 years,maou became a researcher that studies the environment.He married women name aunpo sakura who was in the same condition as maou.They had a sprouse at the body of sakura(sakura and maou has a 6 month baby in sakura's care).One day,there was a heavy rain fall.Maou's child and sakura was in the hospital.A thunder strike came upwards the hospital,and a boy came with a hat in his hand. He started to randomly attack at the houses buildings near him.Maou sensed a familiar sensation which was from his dimension he once ruled and tracked his location,he teleported to the area and saw buildings destoried.The hospital sakura was also in was destroied,he then checked the area from his ability to track sakura but she was nowhere to be found.He lost his temper from the absence of sakura. The boy with hat aaw maou and smiled and said "maou-sama,isn't that you its me,your brother's son kawana."Maou recognised who it was and saw kawana's memory and maou got the situation where the dimension of the mastermaid was there.At last,the culprit was relieved. It was salura.

Maou himself told her how she was able to destroy the dimension in second and there was a miscalculation where she also dies but ends up falling in love with the person she killed.
