Ika Musume aka Squid Girl has emerged from the depth of the sea to take over humanity because of its ill treatment of her home; pollution of the ocean. Bent on conquering humankind, she is furious! Although Ika Musume appears super cute and makes a fantastic spaghetti sauce with her squid ink, she is a terror, wreaking havoc and unintentionally messing up everything she does. Arriving on the surface, when Ika Musume encounters the Aizawa sisters and their restaurant on the beach, she causes a great deal of damage, resulting in her employment to make amends for repairs. Still committed to the task of destroying humanity, Ika Musume must first face the challenge of the Aizawa sisters, their beachfront shop, and the troubles of living among humans on Earth.

In comparing Shinryaku! Ika Musume (Squid Girl) with Ansatsu Kyoushitsu (Assassination Classroom), both anime possess villains with tentacles. Unlike the maleficent trait that follows villains, Ika Musume and Koro-sensei from Assassination Classroom express approachable and pleasant demeanors (more or less, lol). Additionally, the overall theme communicates a similar, playful banter on the destruction of the planet with lots of humor to go along with.

Ryuuko Matoi has been traveling throughout various towns and cities, in search of the person who murdered her father. Ryuuko’s only lead is that the murderer who possesses part of the “Scissor Blade”, which happens to be her father’s invention, can provide more information on their whereabouts and possibly even a name. Consequently, throughout her search, she arrives at Honnouji Academy. At this institution, the student hierarchy is fierce, cutthroat, and competitive, especially under the leadership of school student president Satsuki Kiryuuin. Under Satsuki’s leadership, with the support from the “Elite Four”, they are granted special “Goku Uniforms” enabling the wearer special supernatural powers.

After a rough encounter and brutal defeat with the students at Honnouji Academy, Ryuuko stumbles upon a suit of her own, similar to the Goku Uniforms. Infused with her blood, bestowing her great abilities, together with the Scissor Blade, she tries again to challenge these students; in the hope of gaining more answers about the murder of her father.

In comparing Kill la Kill with Ansatsu Kyoushitsu (Assassination Classroom), these two anime offer a fantastic storyline with epic battle scenes. Additionally, the major element for both signals that an important task/mission must be completed by the characters throughout each episode. More so, there are little bouts of humor in such unlikely settings.

Danganronpa: Kibou no Gakuen to Zetsubou no Koukousei The Animation (Danganropa: The Animation) is about a group of 15 students attending Hope's Peak Academy, a very prestigious school that requires high marks and the most talented applicants. With the perception that these 15 students have gained entry, they are actually placed in a classroom with no visible exit. Present with the students is an adorable teddy bear, Monokuma, who actually is their administrator. As Monokuma instructs the students on how to escape, which is also the way to pass the class, the students must “off” each other one by one without being discovered.

In comparing Danganronpa: Kibou no Gakuen to Zetsubou no Koukousei the Animation (Danganropa: The Animation) with Ansatsu Kyoushitsu (Assassination Classroom), they both share a very similar outline of a classroom environment and a non-human instructor that is not threatening nor menacing in appearance. Furthermore, the students are placed in a position where they must “kill or be killed.” As well as an array of colorful characters, across each episode for both anime, each instructor forces the students to become killers in quirky and bizarre circumstances.

Eikichi Onizuka is a former biker gang leader. After observing the influential sway teachers have over their students, Onizuka decides he wants to become a teacher himself, although at first, for unlikely and selfish reasons. During his studies, Onizuka learns that his motivation has changed and actually wants to educate for the right cause: changing the lives of students he meets. Finally reformed, Onizuka begins teaching. Onizuka utilizes a more practical approach, incorporating life skills in his lessons. Greatly against his unconventional methods, school administration tries everything to make sure Onizuka is out of their hairs for good. However, identical to his own character and background, his students are greatly benefitting from his lessons.

In comparing Great Teacher Onizuka with Ansatsu Kyoushitsu (Assassination Classroom), Onizuka Sensei and Koro-sensei are both unlikely teachers. They are similar in personality and greatly obsessed with women. Most importantly, they share an immense passion to one of the main components to the education occupation: making an impact in the lives of their children, both inside and outside the classroom setting.

Baka to Test to Shoukanjuu (Baka & Test – Summon the Beasts) focuses on Akihisa Yoshii and his classmates of “Class F.” In a school where academics and placements are essential, Akihisa and his classmates are considered the “baka” of the school, i.e., the dumb idiots. At the bottom of the chain, Class F misses out on the exciting privileges and perks of the upper classes. As this frustrates them, Class F bands together to attempt to climb the ladder. When Class F proceeds to take on the other classes, they have the ability to battle each other by summoning beasts with strengths based on their test scores. Across the storyline, many members of Class F unleash knowledge unbeknownst to other students, increasing their strength and status.

In comparing Baka to Test to Shoukanjuu (Baka & Test – Summon the Beasts) with Ansatsu Kyoushitsu (Assassination Classroom), the similarity of both rests on the comedy of low ranking classes being constantly bullied by others higher in the hierarchy. Moreover, as both anime move further into their stories, Baka & Test – Summon the Beasts and Assassination Classroom highlight the underdogs progressively climbing to the top. So who’s getting the last laugh now? 😛

In a world where a majority of the population is born with a superpowered “quirk,” Izuku Midoriya was, unfortunately, the other percentage born without abilities. Nonetheless, Izuku has hoped and dreamt all his life of becoming a superhero, powers or not. However, the only obstacle in his way is the entry exam for the top rated academy for heroes. In any instance, Izuku has done constant research on how to become a hero and finally his efforts aren’t wasted when he meets his ultimate idol, All Might. Fortunately for Izuku, All Might has chosen him to inherit his ability! Consequently, with training from All Might, Izuku studies, is drilled, and lectured on the essence of becoming a hero, slowly ascending the ranks at U.A. High School.

In comparing Boku no Hero Academia (My Hero Academia) with Ansatsu Kyoushitsu (Assassination Classroom), both are similar in that they feature a pupil being taught by an expert in their trade; the best of their kind, in an institution built on fighting/killing. Further, the main character(s) for both are placed at the bottom rung of the chain, but develop gradually over time. Coupling this, their mentor (All Might and Koro-sensei) are huge supporters and only want them to succeed.
