I don't have much to actually say about this one, even in the longer full review I wrote of the series, but yeah; I like it. The manga starts out almost like it'll be a fanservice series, but it's not really -- it's a quirky series about a weird high school girl doing weird things (often with makeshift inventions). She also hangs out with adorable friends a lot. It's silent, it's funny, it's nice.

A manga with very few words, yet can still make you laugh. Very enjoyable and relaxing to read.

Art is good (basic shounen style art [Yes, I am aware it is a seinen])

Characters have limited complexity because.. Well.. Dialogue is pretty non-existant. However, the mangaka has gone back to show key happenings between the protagonist and her friends, which did give some level of insight into what their relationships are based on.

Story is pretty self-explanatory. A slice-of-life manga of a high school girl who is quite eccentric and carefree. It's easy to follow even with the lack of words (there are some where it is needed, but it's very minimalist). The manga is more for relaxing with some lighthearted comedy. It's funny, but not so much so as a gag-manga would be (Don't expect this to be like Daily lives of Highschool Boys or Beelzebubb funny).
