Genre doesn't matter, as long as the MC is a fallen angel or angel, literally not figuratively. No BL, nothing against it just not my cup of tea. Both female and male MC accepted.
Mad God/Kuang Shen, MC is a human-demon(fallen angel)-"beamon" hybrid. He's got black wings and can transform (berserk), which gives him red ones instead. Though the novel is so so and it's written mostly in first POV.
