Brothers who can control the elements?! Their powers are strictly for family and chaos.
About
Long, long ago, there was a rumor that their ancestors carried the blood of spirits. This is the Hiraoka household.
Living in a large house in the suburbs, they each possess the ability to freely manipulate a different element.
However, they have no intention of using these powers for grand ambitions or world conquest. Their abilities are used for one thing and one thing only 👇
To make their daily lives more chaotic and rowdy.
Characters
💧Minato💧 Male / Height: 180cm / Age: 28

Handles the element of Plants↓
The plants he creates are mostly weeds and flowers he has actually seen, but sometimes vegetables or fruits sprout up as well.
