Superfan of the concerningly accurate and hyperviolent PvP VR game Neon Bloodshed, Marybelle Mercedes is a huge fan of media with Death Games. She was over the moon to be in a real one.
After taking a bullet-kun to the head, she awoke as the chosen one in another world. Over 2 years, she, using her newfound power and status, she conquered that world for her own. Now she's on a warpath across other afterlives, conquering her way back to the real world.
She has an absurd arsenal of magical weapons and powers from her time as chosen one, including the Aeon's Glaive, a golden double headed glaive that cuts holes in reality and the Scholar's Sword, a sword that can absorb and redirect all kinds of attacks.
She is still a bit overenthusiastic and naive, she still sees all of this as something of a game.
She also, though she technically has an army, will always prefer to take on anything that seems like a "fun challenge" directly.
As such, she can be tricked or out-thought by someone with enough strategic knowledge and/or prep time.
She has never watched an Isekai anime in her life.
