Let's Laugh at This Beautiful Day

When Izumi Akira came to this seemingly ordinary world, he was a salted fish.
There are two lovely younger sisters, both parents at home, have a car (bicycle) and a house.
There are no peculiar talents and golden fingers, only a thicker skin than others.
When Izumi Ming met Satania and Gabriel, a group of seemingly peculiar humans, he was still a salted fish.
Even if he knew that they were actually angels and demons, there was no way he could become a more powerful salted fish.
When Izumi Ming met Kato Megumi, and his relationship with her gradually warmed up, and when the two even started dating, he was still a salted fish.
Don't do big things, just flirt with girls and fall in love every day, and enjoy your peaceful daily life.

When Iquan Ming spent the Shura Field and decided to open a happy harem where everyone could be together, he realized something.
Even though he is still a salted fish with no specialties.
And it is about to become salted fish dregs (salted fish + human scum).
but……
If it can bring good laughter to everyone's daily life, even if it's just salted fish...
Then I will persevere and be a salted fish with only dreams.
——This harem, Quan Ming and I have decided! ...
