From episode 1 I could tell this was nothing special. The comedy was bland and unoriginal usually resulting in Chidori getting mad at Souske and then hitting him. Are your laughing yet? NO.... well get used to it because that's at least half of the series. The other half is a military mech fighting show that barely scratches the surface of what it could be because it decided it wanted to focus on highschool comedy too. The writers did a terrible job with these two concepts because they don't mesh together at all. It doesn't help that the music is limited at well it has like 4 soundtracks and they're generic.
I put this as background noise after episode 4 and I'm glad I did because my instincts were right. This anime is boring at straight up 5/10. Sousuke and Chidori are terrible main characters. Chidori is annoying and useless. Sousuke is as bland as flour. It took him 20 episodes to show genuine emotion where he wasn't taking like an unsalted cracker. The show also had a weird fascination with showing panty scenes in the first 7-8 episodes, ruining any serious moments.
The only reason people ever liked this show was because they're was literally limited options on what they could choose to enjoy. Times have changed we have like 50 new anime to choose from each coming season. Not to mention the internet gives people quick access to better older anime whether its from a legal or illegal site. There's a reason people don't talk about this show its just forgettable.
