In/Spectre is a supernatural-drama anime that touches other genres such as romance and mystery. We have two young people here, a couple might be an overstatement since at first, their relationship seems like a one-sided affair. Added with an ex-girlfriend in the story, In/Spectre presented a stunning crime-mystery story that involves a supernatural cliche.

Talentless Nana

One of the fall 2020 anime series that surprised me seriously. Talentless Nana presented a battle of the talented and a sole talentless spy among their ranks. In most cases, we had seen Nana, the talentless had killed various talented people in their group and tries her best to deceive the others until one of her classmates got suspicious of her. That classmate is Kyouka, then we had seen them clash on various occasions when Nana keeps on doing her mission of eliminating the talented, while Kyouka keeps on finding clues and proof to unveiled Nana’s misdeeds. The mystery begins when it seems like there’s more to the island where the story is set, a dark tragic past, and another murderer is mixed up in their group. This is an anime of the game Among Us, and everything is a mystery until all truth comes to the surface.

Here’s another mystery anime from 2020 that I believed people should check. The visuals and the soundtrack are absolutely stunning and beautiful. The characters are fun to be with, and it has the historical set up that looks nostalgic. Story-wise, it decent as it follows our main characters as they solve various crimes, albeit they are not detectives: one is a scholar, and the other is a novelist. While the mystery cases seem shallow or uninteresting at some point, the story truly revolves around the delicate relationship of the two main characters which I felt a bit unconventional but also normal for friendship.
