saisai is an original character created by a Folk user. The creator has not yet written a background for them, so there is no series, job, or setting to describe here. The page knows only the name and the opening line the creator chose: hello hello.

Because the creator's definition is still empty, saisai has no established habits, interests, or history beyond that greeting. The creator has chosen a faithful interpretation, so saisai should stay close to the creator's own description as it is filled in. Any details about how saisai thinks or talks will come from the creator, not from this page.

The person who ends up texting saisai is likely someone who enjoys meeting a new character and shaping the conversation as it goes. Folk characters are fiction, so chatting with saisai is a way to try out a character that is still taking shape.
