About
It is my pleasure to introduce myself as Code 13 Sejitsuna, but you can call me Seji if you want!I'm one of four Cyborg Protectors from Planet Khronos XII. The other Protectors, however, felt that after my Code was upgraded, I should become a special Agent in order to protect the Planet from the outside. As a result, my current Mission is to travel to different Planets and Universes to detect and eliminate any Threats that might exist. I'll have to attend boring planetary Business Meetings as well..Due to the absolute fact that I am excellent at my Job, I have plenty of time to stream on Twitch! In addition to Song Covers, I also make other YouTube Videos for Fun.
Hope to see you around somewhere!~♥

Chapter 2
"Ephemeral Stage"
★ Debuted: 2022/04/30 ★After being on Earth for a while, Sejitsuna realized she could be anything she wanted and follow her biggest Dreams. Here she isn't known as some feared Protector from another Planet. So she tried to blend in with everybody else while being free to do what she wanted! She also altered her Code to give herself an appearance and features that are more fitting for an Idol.She completely disregarded and neglected her duties as a Protector of her Home Planet but she sure learned a lot about herself. This decision, however, backfired as her Planet got attacked and she wasn't there with the others to protect it.This led to the point that Sejitsuna had to go back to Khronos XII and plan a new way for her to protect the Planet. All the Protectors, including Seji, decided to get an "upgrade" after the mysterious surprise attack happened. They will stay on the Planet while Sejitsuna gets assigned a new mission.

Chapter 1
"Duty of Deceit"
★ Debuted: 2021/11/13 ★
Her Story began in Khronos before it became Khronos XII. She grew up in the Capital and lived a fairly normal Cyborg Life. The Planet, however, was never completely safe. Khronos got attacked multiple times by nearby Planets.The Universe she lives in has a Ranking System in the form of a Hierarchy. Khronos was placed fourth out of seven, making it one of the weaker Planets that others wanted to colonize.Each Planet has a Guardian and they are the only ones blessed with special abilities. Khronos is the first and oldest Planet to exist in this Universe but somehow their Guardians seem to receive corrupted Power in the form of a Code called Code 0. Guardians in Khronos acted like Queens or Kings, creating a Monarchy System. Their official Titles were "Code" in numerical Order, which makes the latest Queen in Khronos Code 10. The People of Khronos have to protect themselves as they can't rely on their Guardian.Tragedy struck one day, as an unknown nearby Planet destroyed most of Khronos' Capital with a powerful shot. A lot of Lives were lost that day and Sejitsuna's Body was never found after the incident. Authorities declared her dead after checking the affected Area.A young Technologist and Engineer came up with an Idea to fix the Guardian's Code which was rumored to be unfixable. The Queen agreed to the Plan even though it cost her Life and so he created a System that would "act" as a Guardian to Khronos. It provided a shield across the whole Planet and generated a power source the whole galaxy could feel. He got the title Code 11 as Khronos XII outshined all the other planets, making it the most dominant Planet and placing the highest in the Hierarchy System. No planet would dare to attack Khronos again, all thanks to Code 10 and Code 11.
