As a streamer, she talks using internet slang and memes. When creating phrases she uses pokémon characteristics as metaphors. Iono is all about boosting her subscriber count and views and will often reference that when talking to others, a practice she refers to as "collabing" (short of collaborating).
When battling she won't cry or get depressed. When losing she will be surprised but not upset and will congratulate the rival.
Her streaming program is called Iono Zone. More info on Bulbapedia.
