Sinis and Dex

Resumen

The twin Mecha-Ude that have combined (derized) with [Aki.](https://anilist.co/character/133180) They have grown up with Aki ever since she was little and are very loyal to her. They are twins, but they are polar opposites. Sinis is rather calm, while Dex is rather crude. They like Aki and dislike detailed work. (Source: Official Site)
