Ayumu Tamari suffers from a condition known as "Crystallization Syndrome." In moments of high stress, parts of his body begin to crystallize and become extremely difficult to move. Unfortunately, Ayumu's severe social anxiety makes him completely unable to speak to anyone in his class, and ultimately causes him to crystallize so frequently that he has to repeat a year in high school.

Ayumu's only solace is his homeroom teacher, Kouya Onihara, whom he affectionately refers to as "Oni-chan Sensei." Kouya collects and studies crystals, and he finds Ayumu's crystalline body both beautiful and fascinating. With his stress from school compounded by the complexities of a forbidden student-teacher relationship, Ayumu struggles to find normalcy in his life while managing his emotions and trying to prevent complete crystallization.

To start off with, let me just say that I am not one for long tedious anime reviews so this will be a short but concise one. So without any further ado let me begin. :D

I have personally fallen in love with all of the previous episodes within this 'Kono Danshi' series so when I heard of this new installment I HAD to watch it and surely enough I was not disappointed. The anime centers around a shy boy who then falls in love with his teacher. Along the way you are gripped with emotions of sadness, empathy and then overall joy.

I will have to start by saying that I was not impressed by the latest of Soubi Yamamoto's works. Having been a big fan of her previous animations (Kono Danshi Uchuujin to Tatakaemasu, Kono Danshi Ningyo Hiroimashita and Robotica*Robotics) I was super excited to watch Kono Danshi Sekika ni Nayandemasu.

I found that once the OVA had actually began, it was littered with clichés and thematics that belong to corny BL anime/manga, and often the 'romantic' lines felt rushed and forced. The exchanges between the two main characters, although endearing at times, quickly became irritating due to the corniness to the scriptwriting. However, read more

I fell in love with the other two OVA's that were related to this series, and was excited to watch this one. The art style was unique like the rest of the OVA's, but this probably was my least favorite of the 3. The story is pretty cute (though a tad bit too cheesy for my liking), and the main characters in this have a lot of deep emotions that people can easily relate to (especially if you deal with being socially anxious). I think this OVA shared some great insight, even if I felt that the story was a bit rushed and at times read more

This is a great anime.
I think it is very underrated. Although it seems to be a normal teacher-student romance it is very deep. I think that the synopsis sells it short. The art was iffy at times but it was easily made up for in content. Any OVA can have small issues but this had those mostly weeded out. The characters were well developed which is hard to do in an anime this short but it was done wonderfully. Unlike some animes this short the characters did change over the corse and it did not follow normal anime tropes. It was a very original read more
