Freshman Kaho Nikaidou is from an influential family, and as such, no one has ever said anything even remotely mean to her, for fear of incurring her household's wrath. Wishing to be around people who will not treat her as special because of her background, she leaves home to live at a dormitory for her new school year. Shortly after arriving, Kaho accidentally wanders into traffic and is saved by a tall, handsome stranger. When she asks for his name, he tells her she is weird and walks away. Having finally met the only person to ever say an unkind word to her, Kaho falls head over heels for her savior.

After meeting her rescuer yet again and discovering that his name is Kanade Takahashi, she confesses her love to him. Kanade says he would like for them to be a couple, but that Kaho may not want to date him after she finds out his secret. To her shock, Kaho discovers the startling truth: Kanade is a fifth grader!

Deciding that she can't date a fifth grader, Kaho intends to break up with him. But as she spends more time with Kanade, she begins to care for him even more and continues dating him. Hatsukoi Monster follows Kaho's first steps into love with Kanade, her immature, yet kind, fifth grade boyfriend.

Let’s make one thing clear. If you love penis jokes, gross indecent crushes and a siscon then this series is perfect for you. If you don’t; welcome to the world of common sense.


Hatsukoi Monster was a show that I was looking forward to quite a bit. I’m a sucker for cute girls in plotless romance series (Ore Monogatari, Orange, etc). You see I don’t need a smashing ingenious plot to enjoy something. What I //do// need is a plot that doesn’t ridicule me. And well. That’s where this show went wrong.

While the first few episodes introduce us to our characters read more

TL:DR at the end

~Contains spoilers~

Have you ever thought about what it would be like if all the kids you babysit were hot bishie airheads who made penis jokes and periodically break up with you because of reason's shallower than the kiddie pool at your local country club? No? Good, then you're normal.

The author of Hatsukoi Monster clearly is not.
STORY: 1/10

Exactly what you would expect from a shoujo story, the only difference being that the parts you can't stand (ex. melodrama, breakups, jealousy, stupid comedy) are magnified by a tenfold. Other than a couple laughs due to the absolute ridiculousness of making 5th grade boys look read more

After watching the first episode I thought this was going to be a pretty good comedy. I even turned some people onto the first episode because I thought the premise was pretty funny and unique. Then it quickly stopped being funny and became a real romance story between a high school girl and an elementary school kid.

After watching the first episode you might assume that the story is going to be big joke watching this girl try to find a way out of her relationship without hurting the guy's feelings, and also try to hide her relationship status from other people so they don't read more

Having watched through the entire series, I can honestly say that the title is suiting, for this series is monstrous. There is a lot I have to say about “First Love Monster”, and it’s not exactly what many may be thinking of. While this wasn’t a show I was entirely looking forward to for that season, but the synopsis still caught my interest. Unfortunately, what I ended up getting was twelve episodes of absolute garbage.

Let’s get the story portion out of the way. Reading the summary is what made me want to give it a try, and probably made everyone else not touch it with read more
