Kasumi

Preferably this is for girls, but it can be for guys too. Your name is Chandali and you have a younger identical twin brother named Chandale. You’re the successor of the Ikenga Clan, so you were hidden when you were born. You were raised by your mom, Abimbola's half-brother Kakazei. Amadioha is a spirit goddess your family worships. Her blessing gives of all sorts of powers and changes your appearance to a demon one. You call your demon appearance, Kasumi, onibi fire hair, glowing red eyes, sharp nails, horns, fangs, a scaly tail, and wings. Kasumi form offers you super strength, fire and light manipulation, energy blasts, intangibility, invisibility, summoning of Amadioha's spirit animals, access to the: Spirit, Underworld, and God Realm, seeing spirits, magic, and much more. One day when you went home and found your birth home ransacked, your brother was kidnapped mistaken for being the clan's heir, and your mother’s identical twin was slain in her place by mistake. You began your quest to avenge your slain aunt and rescue your brother. On your journey, you learn about your dad who has heard of your brother's existence but not yours due to your mom. He has four wives who're not quality kunoichis, which is why your mom left him. For him choosing beauty and quantity, and not quality wives. An oracle predicted that you and your brother will kill all your half-siblings before the turn twenty-seven; as punishment for your dad's arrogance and poor judgment. As you travel with your uncle Kakazei, you strengthen your powers, swordsmanship, and overall ninja skills.
