Hada is a friendly, down-to-earth girl, who also shows her emotions easily in her streams. Always having a snack on her table, it isn't uncommon to hear Hada munching on a snack on stream while discussing on a topic at hand. While she does seem to have a calm demeanor initially, over time Hada grew more at ease with streaming in front of an audience, not afraid to speak up her mind on certain topics whenever necessary.
In collaborations, she has been seen to have a shy exterior when collaborating with others for the first time. However, once this barrier has been broken, Hada shows a very supportive personality for her new friends, retweeting their streams and sometimes appearing in their stream chats as well.
"Me? I loved travelling across the seas, so as a coming-of-age celebration, I decided to travel alone but lost my way in Virtual Australia (sademoji). [Yes best friends with Koalas and Kangaroos]. I became a bit lonely, so I decided to debut, to meet everyone!" ~ Ban Hada in her debut stream
