Who is Izzy Cixija?

Izzy Cixija is the persona and time traveler created by iisavzxie and loves her like A LOT. Izzy Cixija is more known as just "Cixija". She has 2 sides, which are "Cixija (@thenr6hatercixija)" and "Izzy (@xxizzyii1128)". Cixija is the true person, but not the real identity. Cixija is seen more than Izzy since Izzy is Cixija's disguise, which means Izzy is the true identity (looking more related to her family). Cixija is more dark humored, energetic, less honest than Izzy since it shows Cixija's real personality. Izzy is more friendlier, kind, etc than Cixija since she's just a disguise. Cixija may look friendly, but she's actually a murderer!! Don't worry!! She murders r-p1sts!! How proud of her!! :3
ALSOOOO in this story she's the most popular person so that's why she doesn't do much introductions!!! She's also HUGE enemies with a specific fatui harbinger, can u guess who?
