As somebody who absolutely loves Paru Itagaki and everything she writes, I was overall pretty stoked about this manga! I think that Itagaki had some interesting things she wanted to say with this manga, so let's get into it.

Story: 8/10
Sadly, this story was not as strong as Itagaki's other mangas, but I loved how bizarre and surreal it was. I think Paru's goal with this story was to show that not everything in relationships is all black and white. Some people need different things, and overall that's what makes relationships and love beautiful. I think this message got bogged down a bit with Paru attempting to explain the MC's condition and how it worked, and I think this story may have been written on the fly. Regardless, for something as short as it is, BotaBota is a ride and is worth reading.
Art: 10/10
What can I say, I'm a bit bias. I love Itagaki's art style and I love how she draws people. You can tell she's a bit out of her comfort zone considering she had been writing Beastars for years before she wrote this. Paru tends to go for very stylized illustrations, and overall I think her art style is put to work well here. As always, the paneling and how everything flows together is spectacular. (This is one of Itagaki's strengths for sure.)
Character 8/10
This story follows a woman who has a condition that causes her nose to bleed life-threatening amounts when she touches something dirty. Itagaki goes into how this has affected her life and her mental state. I think she does this fairly well, although she's done psychological stories a lot better in the past. Not bad for sure, but it could've been done even stronger. I am not going to be too critical about this since this was a very short manga that didn't appear to be Itagaki's main focus at the time.
Enjoyment: 10/10
What can I say, it was a fun read!
Overall: 9/10 I think this story was fun and surreal, but a bit bogged down by blurry messaging. I can tell what Itagaki was going for, but it didn't tie up right in the end. Overall not a bad story and worth your time In my opinion. :)
