- Wacky Homeroom: Class 1-5 just happens to contain a lot of the main characters.
The main protagonist of the series, Takuhiko is a perverted otaku who spends most of his time watching anime, reading manga, playing video games, and doing any other activity that would consider him lazy. But when his mother confiscates his computer, he is forced to interact with people, much to his chagrin. But he makes the best of his situation and promises to build the best Harem he possibly can.
- Agent Scully: Played for Laughs, as he dismisses Misery's claims of being magical as Chuninbyou despite being confronted by a Demonically Possessed Misery at least twice.
- Bigger Is Better in Bed: Claimed to have a bigger "manhood" than Keiichi among other things.
- Book Dumb: He barely met the required test score in order to get into Sakuragi High.
- Cannot Talk to Women: Has a hard time talking to women at first, but eventually gets used to it by the time he meets Neko. Case and point, when he compliments a girl...on her breasts due to having nothing better not come up with.
- Casanova Wannabe
- The Cuckoo Lander Was Right: He was correct in that Sakutaro was faking his cuteness.
- The Ditherer: Wants to focus one the Harem at large rather than "the one" just yet
- Entitled to Have You: Feels that he deserves women due to spending several years isolated, albeit by choice.
- Erotic Dream: Before he knew his tutor was Aya, he dreamed that she was a stereotypical Yuri girl accompanied by her more masculine-looking "best friend". The dream ends before the good parts can happen though.
- Hypocritical Humor: Saying he's a Hypocrite is an understatement. In one case, he calls one of Neko's Otome Games about vampire wizards "stupid", but says he likes a game that's basically the same except with the genders reversed.
- Jerkass: Has plenty of moments like this, especially in early chapters.
- Lazy Bum: Is trying to improve ,but he'd rather play video games and watch anime rather than study.

- Loony Fan: Is this to Mai to the point of being a borderline-Stalker with a Crush. And keep in mind that she's retired now!
- Loser Protagonist: Except unlike other Harem examples, women don't fall for him as quickly as he expects it and in some cases it works against him.
- Mistaken Age: Has been mistaken for a middle schooler if not even younger on a few occasions. However this is one of many Berserk Button.
- Moe: Not only does he survive off of it, Keiichi argues that he provides many male examples such as his short height and large eyes. Unfortunately he wants to seen as sexy and not cute.

- Nosebleed: Claims to have had frequent ones ever since he was a child.
- No Social Skills

- Perverse Sexual Lust: Takuhiko prefers 2D women to the real thing with some exceptions.
- Rose-Haired Sweetie. Subverted as while he tries to be the romantic type he is a Jerkass with No Social Skills.
- Siblings Wanted: Always wanted a little sister...however he got a brother instead. Although she probably would've turned out the same way anyway.

- Socially Awkward Hero
- Suspiciously Specific Denial: Denies that he ever thought of infiltrating an all-girl's school Disguised in Drag. What's strange is that he's pretty shameless about his other turn-ons.
- Tiny Schoolboy: Takuhiko is rather short compared to even some of his female classmates, which he is rather insecure about.
- This Loser Is You: Parodies otaku that are the target audience of romance and Moe.
- Yuri Fanboy: Definitely proves himself to be this instead of just thinking Girl on Girl Is Hot with a Dream Sequence involving two lesbians styled like something in the Yuri Genre.
First introduced at the end of the second chapter, Neko seems like the perfect girlfriend for Takuhiko. She's attractive, an otaku, and oozes with Moe. Seems like the perfect head of his Harem. After they actually meet, she reveals herself to be a crazy Weaboo that thinks they're reliving a past life. Now Takuhiko is very unsure.

- Cloudcuckoolander: Neko is rather ditzy and suffers from Chuninbyou.]
- Genki Girl
- Giver of Lame Names: Assuming her story of reincarnation is fictional, she's this for adding an "-a" at the Latin name for cat ,"Felis", and just calling the prince the Latin name for rabbit.
- Gratuitous Japanese: Neko's dialogue is written in the style of when translators feel the need to leave certain words untranslated despite having normal English overall. Her normal Japanese is apparently fine according to Takuhiko, it's just we don't hear that thanks to Translation Convention.

- Occidental Otaku

- Reincarnation Romance: She quickly realizes that Takuhiko looks like Prince Lepus and thinks it's meant to be.

- Thinks Like a Romance Novel: Phrases things like she's a character in a Romance Manga.
- Whole-Plot Reference: Neko's entire story about her past life and being a Magical Girl is almost a word for word rip-off of Sailor Moon. Even Takuhiko lampshades this.

- The B Grade: Would've gotten into a prestigious school if she had only gotten that one point on her entrance exams.

- Cram School: She attends one in-between her after school club and tutoring Takuhiko.

- Parental Neglect: Out of nowhere on August 23, 2016; Takuhiko's Waifu posted a strange picture on her DeviantArt of a black birthday cake with red pentagrams. The accompanying text seems to be a note written by a mother who is apologizing for forgetting her child's birthday. It was later revealed in the following chapter that the woman who wrote the note is Misery's stepmother who is so forgetful that she doesn't even know his real name.
- Parent with New Paramour: While Shion despite shows no signs of a Wicked Stepmother ,Misery is sort of justified since her forgetfulness causes her to be pretty neglectful.

- Bromantic Foil: He's basically the opposite of Takuhiko in every way.

- The Social Expert: Although he is unsuccessful in teaching Takuhiko even the bare basics.
- Super Gullible: Easily fell for Takuhiko's Cobra Hydra trick.

- Bishōnen Jump Syndrome: It can be argued that her work suffers from this.

- Yaoi Fangirl: She apparently has plenty of gay couples in her work.
