As usual, im on purpose picking a series that not perfect (around 7 - 7.5 on MAL) just to find any anime that can intrigued me, to find a hidden gems. Just take note that I will spoil MAJOR PLOT POINT in the series. Watch first episode first, then come back here to read the review.
Anime is standard cliche underdog story. I mean, it started with someone who have no talent among an elite school full of student with talents (super ability) just to prepare themselves to fight enemy of humanity when they grew up. Then there is rumor that the enemy already infiltrate the school in order to take all students out. As the body count raise up, how will our protagonist discover the true killer among the school mates? Will all truths finally revealed?
► Show Spoiler
As i mentioned in the picture, the anime have potential. But it is inconsistent with tone shifting between serious & playful school story. The anime production arent great, no other memorable things to say except unique concept.
