This isn’t trans Denki. Trans Denki would stay as a boy. It said in the beginning that he is trans and was a girl but now a boy. As soon and he came out as Trans people started calling him a girl which is not his pronouns. Unless he was originally a boy and turned into a boy. That is how trans works. Not how you are doing. No hate but I’m just correcting you on it. I have a lot of trans friends so I know about this stuff.
As a trans female to male person, I don't like the representation that thank he is giving off. Being called a girl will, even though you identify as a male, will take off of your mental stability, it doesn't seem thank you, feels any sort of depression or dysphoria wow being called a girl.
Is denki Trans or bi-gender? (bi-gender is where you go from gender to gender like one day you feel like a girl and others you might feel like a boy and my be some times they feel non-binary or gender-fluid and the pronouns go with that days gender like a girl day you use she/her or on non-binary days you use they/them stuff like that just a explanation most people don't know what bi-gender is.)
What you are describing is genderfluid. Bigender is identifying as 2 or more genders at the same time. I am Bigender because I identify as a boy while also identifying as non-binary. Genderfluid is where your gender fluctuates between genders. A way to tell this that the term ‘bi’ usually means 2 or more. The term ‘fluid’ just means fluid. Not always the same, fluctuating, that kind of thing. I don’t want this to sound rude and I apologize if it does.
