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.

There are these idiotic teenagers who think I consider them friends, and since I've known one of them since my junior year of high school, I feel obligated to keep that up with her friends too. The fact that the same situation is presented with the main character in this anime, makes me love the characters even more. It's crass, elementary school level humor never ceases to be funny. The deuteragonist, Kaede is and I'm kind of ashamed to say this as a 20 year old, pretty hot. Inside and out. As Nikaido struggles to make all of her roommates happy, she learns important lessons ...

Mixed Feelings
I did not read the plot summary and such. There is 40% I would not have watched if read it and only watched because looking at cover art, everyone looks high school age at minimum, except for Kaz who looks like a girl, so I would be wondering who the hell this "5th grader is". I gave a 7/10, with 4/5 and 5/5 on lots of episodes, being interfered by "cons" that felts 2/5 at best. Cons are enough reason to justify the 5.46 MAL grade by 41358 users.

-high schooler "in love" with primary/elementary schooler
-main character has her issues, can't explain
-extreme stalker perverts
-incestuous stalker perverts
-some ...

AHHHHHHH I give this a -100,000,000,000 I hated this soooooo much!!!!!!!! It was so wrong!!! Don't get me wrong it had slight potential the animation was beautiful everyone was beautiful the plot and the characters personalities sucked!!!! Kaho literally a teen, 15 to be exact. Okay good for her she's short, she's cute, she's your average loli/school girl. Kanade is a 10 year old that looks like he could be rocking 17 years old maybe even 20 years old, he's 10, TEN YEARS OLD!!!!! For some odd reason he has fully gone through puberty at the age of 10. But it's not just him it's ...
