Raiden Vasherion is a genderless jRPG and Fighting Game vTuber who was created by MikelAL93 as the mascot of his twitch streams. She is there to make sure that everyone has fun watching Mikel and the games he streams on his Twitch channel.
While Raiden is agender, Mikel revealed that he chose to make her as such since he wants to twist things up with her as a whole. However, despite this, she refers to herself as female as per his recommendation.
Part of the inspiration for Raiden comes from Seth in Street Fighter V, who himself is agender, but uses a female body as part of his default outfit (his male body is also in the game too) and a male voice. Raiden Mei/Raiden Shogun/Acheron is another character whom inspired Raiden Vasherion as far as her appearance goes. Whenever Raiden speaks, Mikel will speak through her with his voice, a reference to Seth as well.
Raiden is a member of the Bracer Guild.
