Before you read, about the story and warnings
Harem and first three love interests:
This is a story with a futa protag. And it isn't your ordinary harem.
I'm a big Ty Lee and Azula fan. They're both waifus.
Incest with Mc and Mai.
-----------------
Fusions skill:
The fusion power in this story is taken from King Kais from db.
Some harem members will be integrated into others with fusion power. They can be uncombined. The ability of fusion goes to other stuff like items too.
-----------------
Protag's look:
Young Najenda from Akame ga kill. (minus the hair and eye color, ponytail comes later)
The story starts in ATLA, and the mc will be Mai's trap sister. (Girl with dick and balls)
The mc can do all things men do and impregnate his women. But he'll accept to dress like a woman and look like one after some point. (Don't think too much)
-----------------
Mc's affiliation:
Not a villain. Not a hero complex. Ordinary person who can save others but puts himself and his loved ones first.
Mc has a bit of a bias against certain characters. He doesn't like people with idealistic and soft mentalities.
