Set in 2042, the XEi is an alien government that has taken over a large portion of the galaxy and has colonised a large amount of dimensions and planets. Their main goal is to obtain as much of the universe as possible, by recruiting worthy creatures to work for them and to colonise more places for their people to live and work from.
The story focuses on three characters; Axel Drous, Tüun Vik, and Vaa'Spark. Axel was originally an ordinary human boy, but after an encounter with a group of unidentified aliens abducting and experimenting on him, he became the XEi’s first metahuman employee. He uses his bodysuit and emotion-shifting dial to switch between forms and use the powers of the alien creatures he turns into. Tüun is from a race of humanoid, buglike aliens called ‘Scvorpons’ and is an ex-criminal who was employed by the XEi in an effort to clear his name. Vaa'Spark is a cyborg, who used to be a human much like Axel, but was taken by the XEi hundreds of years ago and fitted with technology, while erasing her memories and giving her the name 'V11.VAA-SPA'RK1.’ She works hard for the XEi, but is determined to one day regain her memories so she can return to her old life.
Axel meets Vaa'Spark not long after being recruited by the XEi, and she becomes a mother figure to him as she shows how their system works and what each role in their government does. The two end up assigned to rescue Tüun, who was breaking into one of the colony buildings and had set the area on fire during break-in. After Axel comforts Tüun and tries to get him to see a better light, the bug decides it’s a good opportunity to clear his criminal status and assigns to work alongside Axel and Vaa'Spark.
