Mieruko-chan is one of the best mangas I've had the pleasure to read recently. It's a very young publication, and there are only abut a dozen chapters out. Despite that, it is already showing a lot of potential and talent.
The story is episodic in nature. It's not concerned with how the main character got her power to see ghosts, or her progression in skills. It is more like a weekly fill of horror and comedy. Currently it's difficult to judge the story right away since the manga has barely started, but like I said, it's showing potential that it can achieve something substantial even with its episodic nature. For example, chapter 4 + 4.5 melted my heart. While he characters and plot were predictable, the execution through pacing and art made it brilliant.
Plus the main character, Mieruko-chan comes across as admirable and brave. She always seems to make the best choice in a given situation, and so, as a reader, you naturally admire her. Even the supporting cast is distinct. Her best friend, a younger brother and a rival. They support the story without ever being an annoyance.
My favorite thing about this manga has to be the art. It is simply beautiful. One of the best illustrations of ghosts and monsters I've encountered. Not only the grotesque imagery, but also how the reveals are handled in a panel format is genius. I can't praise the artist enough for how disgusting and primordial he makes his creatures look. Especially in chapter 11. It's a show of ambition, with the talent and skill to back it up. Additionally, the human characters are well drawn every time. Especially their reactions. Although the designs of the characters borders on cliche, but the author imprints his own style so that it remains unique.
Overall, I would highly recommended checking out this manga regardless of your tastes. The only caveat is this: Don't go into the manga expecting a deep story or a dark and twisted plot. While the concept of having to see ghosts everyday might sound inherently spooky, this manga isn't trying to scare you. It's not about that. It's a humorous manga, with strong horror elements, and the humor aspect is derived from Mieruko-chan trying her best to ignore these (incredibly drawn) abominations in her everyday life.
I can't wait to see where the series will go from here, and I hope you join me for that ride by checking out this manga.
