I've never wrote a review before but oh boy is this a disaster
Jibaku Shounen Hanako-kun is a manga that looks really fun and has a quite unique style. I've been following this manga ever since it started yet it turned out to be a huge disappointment.

Story:
A story about urban legends in a school, interesting at first yet actually just a cliche plot. Most of the time the plot is just Nene getting rescued by her har-- friends. Super unrealistic and has tons of plot holes. This mangas only comedy source is Nene's legs. But pacing is the worst part here, it's been 64 chapters and we still have no idea about what is the relationship between Tsukasa and Amane (and no background of Amane either). So many useless drama that cames out of nowhere yet leaves an impact on characters (you know which I'm talking about).
I have no idea where author is going but I have no hope for it either. 3/10

Characters:
Oh god. Here we go.
You couldn't guess such a horrible mc for a manga like this. The whole personality of Nene is just how horny she is and how she has 'radish ankles'.
Can't do anything on her own and always gets in trouble and waits for help from Hanako. She put herself in danger multiple times to get her dreamy harem. A typical shoujo mc but worse.

I can't really say anything about Hanako because we never got any info about him really. A cool ghost boy with really good patience

Kou. Actually the only one that I can call a character.
His first debut was aggressive yet he quickly developed so much. A very nice boy that cares about his friends and tries his best.

Tsukasa gang is cool but sadly we don't know much about them for now.

Overall there are so much useless/cliche characters in this manga. 2/10

Art:
I think we all can agree that art is the best thing in this manga. While it's cute and original, it's also very detailed and nicely done. The whole reason I started reading this was the artwork and is the reason I haven't dropped it yet. 9/10

Enjoyment:
Well, I tried my best enjoying this manga because of how much I love how it looks- But it was impossible with such plot and mc. 1/10

Overall... 4/10 I can't give a lower point when Kou exists and I really like the artstyle.
This manga was a HUGE disappointment to me, like I said. I had very high expections and none of them were answered. Even so, I understand how this manga is really popular and loved, I'm just really salty :P

I tried my best to explain my views on Jibaku Shounen Hanako-kun but I'm nowhere expert in English so I may have not convey my thoughts very well.
