Seiso is a Japanese word that is used to describe a woman's character and appearance.

In a general sense, it means a woman who has a humble character, a clean appearance, uses beautiful words, and has beautiful posture and movements.
On the other hand, in the case of neatness used in the context of Vtuver, the meaning is slightly different.
Specifically, it adds not being lewd to its original meaning.
Seiso: When a lewd topic comes up, she doesn't like it. She skillfully changes the topic to the next one or is embarrassed.
Not Seiso: When a lewd topic comes up, she actively uses it to entertain and enliven the audience.

Seiso: She does not raise lewd topics. She will ignore or scold viewer comments when they are made on such topics.
Not Seiso: She may raise lewd topics to entertain viewers and herself.

Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.

Me: Woah! TLDU!
