Both series are are centered around a main character being a dancer, heading towards a career in dance. Their opposite isn't initially interested in dance, but due to the dancer becomes a dancer or intrigued in the world of dance.

Both series focus on a female centered character group in a survival situation. There's a lot of suspense elements and character dynamics that feel very similar.

The main casts all meet at art school. Honey and Clover focusing more on the college-age adventures and departments, with Hidarikiki no Eren focusing post-college careers and paths. There's both the self-made artists, and those who are considered 'geniuses' as well.

Both series focus on a Prince-like, or at least incredibly wealth male lead character. In both series, the more aristocratic elements are usually played off for laughs and are 'popcorn' type of entertainment.

Both series focus on the diagnosis and the impact of ALS (Lou Gehrig's disease) on a young individual. The larger picture is how ALS impacts the individual, and then the diagnosed person's relationships romantically and platonically. (They also both happen to be tearjearkers on top of it.)

Both titles are centered on a school setting with an all girl's school. Which the level of suspense it different, GGL focusing more on 'battles' whereas Zanokokuna focuses on 'audience approval', the actions of an individual affect the group and the reality of the situation affects the real world.

Both Brave and Battle Royale are based off manga and novelizations. The biggest point of comparison is that both feature high school casts that are sent to a new location where they must survive or die.

Both series focus on a non-traditional main character; 'Ore no Sukato' focuses on their gay homeroom teacher, and '35 sai' focuses on their 35-year-old transfer student. The series' focuses on individual students on a per episode basis, while tying the class together with the overarching plot line, that cumulates at the end.

A similar situation where a group of students is being manipulated by a larger power; 3-nen being manipulated by their teacher and Zankokuna by the unforgiving net and potential setbacks that come with failing. The group must make decisions that will ultimately punish an individual if the group fails, and vice versa.

The idea of pitting student vs. student, instead of a government plan as a individual in charge of a hostage situation. Similar atmosphere between both sets of students.

While both deal with swimming, 'Taiikukan Baby' has romance undertones where 'Dansui!' does not. Both are movies focused around swimming and the struggles swimmers face.

While "Dansui!" is a short drama, "No Breathing" is a movie. However, both are based around male competitive swimming and the trials and tribulations of injuries, coaching, competition, rivalry, and friendship.
