As much as I enjoy seeing Tsubaki being put in her place by Kiritsu, that is only a temporary solution. She needs to be reformed as a person, and that will not happen even if she dates Kiritsu because she would not be feeling the consequences of her actions. I think this manga would be much better if, instead them being on an apparently romantic collision course with each other, Kiritsu finally managed to get her expelled or something. Then the manga would continue to follow his life as he goes to college, has the same problems, and defeats similar dangerous women, etc., instead of this turning into a silly love comedy. Perhaps they would meet years later with her having become a more wholesome person, and then they get together - that would be a great story.
