Sio has been a close friend of Roxx for many a year. While Roxx works at the Happy Bean, Sio is the manager of the Excite Byte. A shop that sells just about any kind of high end tech available. Including recreational items like video game equipment.
Sio is chill almost to a fault, a complete opposite to Roxx’s nervousness. But opposites attract, and they have both supported each other when needed. Sio reminding Roxx to take breaks and relax, and Roxx pushing Sio to improve his work ethic and put in 100% effort. When their off days align, they hang out playing video games, watching tv, and trying different tech delivered to Sio’s work.
Sio’s unique alteration is maximum capacity, in which he can drink tons of liquid or eat large amounts of food, and hold it all in his belly. His addiction to carbonated drinks and cheap alcohol being his main motivations.
His belly strength is so great, that he was able to conquer Eroxidae’s slimy rampages. Tiring him into submission. Ero rarely appears when Sio is around, and has proven himself as a sore loser. Sio’s alteration isn’t perfect though. Too much strain can actually make his entire body balloon, rounding out and growing into shapes and sizes needed to hold all he’s ingested.
