Denpa Kyoushi

Both are high school comedies where the teacher is a helpful, but unusual person. In the case of Assassination Classroom, the teacher is an alien who is bent on destroying the world, while in Ultimate Otaku Teacher the teacher is an otaku who uses stuff he picked up from watching anime to teach class. Both teachers are very helpful towards their students who had a grim outlook on life prior to meeting them. 

The Ultimate Sensei who arrives and gives life lessons to their students. Both of them care for their well being and dreams. One is an alien sensei who tries to get his students to kill him. The other an Otaku. They have an unusual way or style of teaching.  

This is like a deja'vu. When i watched the first episode of Denpa Kyoushi i imediately remembered Ansatsu. Both have a "super teacher" that cares about his students and want them to be happy. While in Denpa Kyoushi we have a brilliant NEET, in Ansatsu we have a mutant .. but that's not really a difference xD Both anime look to teach us something using comedy.  

* Both have ”SUPER TEACHERS” (Koro-sensei & Kagami Junichirou) & ultra annoying chairmans (Hiiragi & Asano) * Both has nice character designs ( Denpa Kyoushi has way better designs ) * In both, we see everyday life of students/teachers while they're at school.. * Pretty nice OST's... characters voices also... * Both have funny moments (again +1 for DK) * Both have pretty serious episodes, but at the end our MC-kun's will always win... ! FFS, WATCH DK if you liked AssClass.... 

Both are about a quirky teacher who seeks the best for his students, even if he must challenge them and take action. Both seek to show that we all have the same opportunity to achieve what we set out to be by being ourselves. 

The animes both have the same teacher and student setting except AK is more about sci-fi, action and comedy, while DK is more on the slice of life, comedy, romance, gender bender and harem. Charcaterwise, in AK the teacher is an alien who wants to be killed while in DK the teacher is an otaku who wants to get his students to be involved in his virtual world.  

Though they're not so similar with the art style, both has this Odd teachers that will do anything just to help their students. 

The baseline approach of a new and improvised teacher is same as Ansatsu Kyoushitsu. However the setting is in a real 21st century world with 21st century problems including the sense of entertainment and much more 

These two anime have the same teacher character as the main character. and this teacher is the same as guiding his students. a lot of advice given by the teacher to his students , that's what makes me love these two anime. the teacher figure in denpa kyoushi is more profound. while the koro sensei in ansatsu kyoushitsu is the same, but the big difference is in the drama. In Denpa Kyoushi does not have deep drama like in ansatsu kyoushitsu. Even though the ending of Denpa Kyoushi was a bit involved (making me curious about the continuation s2) Unfortunately, there is no info about S2 yet, but the ending was very satisfying and cool read more 

Ever assigned to teach a bunch of socially-rejected pupils? Here is your chance. Denpa Kyoushi as well as GTO offer you the chance to laugh of what a teacher can do, if he's also by himself, rejected by society. Although Comedy is not guaranteed in both of the series, the enjoyment rate will change your vision into what schooling means. But most important is that... here they share the fact that they're teaching us what it meant to be a teacher. 

Similarities. Both having the main MC(Teacher) guiding the students to go on the correct path The Main MC originally not suited to be a teacher(GTO-Yankee, DK-Otaku) The MC got accepted to the school due to the principle finding them interesting. 

-Both shows has NEETs as Protagonist's -They suddenly become a Teacher -They help students with problems Kagami has the brains, Onizuka has the power. 

The MC become a great teacher and has some different -Kagami is a great teacher otaku -Onizuka is a great teacher bad boys 

For those who didn't know - Denpa Kyoushi is a stupid clone of the GTO, and if you're tired of it's bottom lvl, check out the original run, you won't regret. 

Takes up a similar concept of helping students to grow up in unique ways! 

They have literally the SAME CONCEPT it's like if great teacher onizuka was an otaku except of a gangster and he was smart.  

Both involves a MC who is forced to become a teacher in a prestigious school. At the beggining, he seem unmotivated and give a really bad first impression to everyone, but later shows that he have lots of knowledge and hidden tricks to teach his new students in order to help them. 

In many ways, the newer series seems to be a straight translation of Denpa Kyoushi into a fantasy world. In DK, the character is simply unmotivated as opposed to the "shadowed past" of RMKtAR's protagonist. However, the personality and appearance are closely analogous, and the theme of "apparently incompetent teacher prevails through hidden talents and love of his students" comes across unchanged.  

Both are about an Otaku who is forced to do a task they are uninterested in by a little sister character. Both MCs are otaku geniuses.
