Nichijou, Tonari no Seki-kun Recommendations
Both shows entertain with frivolous and random comedy. Nichijou has full episodes and more characters while Seki is shorter and, so far, focuses on only two people.
Expect random comedy, humorous dialogues, and in general, stories made out of arbitrary daily life events. Nichijou and Tonari no Seki-kun are anime series that follows an episodic format with no direct or linear storyline. The stories are simple with gags and fun. They both take place in a school life setting. The main characters from both series creates a comical environment with slice of life attributes.
Simple animation (at first glance) that uses over exaggeration as a main key for the comedy and the setting is in a school.
Random short stories of few minutes that (for Nichijou: mostly) take place in school.
Tonari no Seki-kun features one story per episode, Nichijou features multiple stories in one episode, sometimes even split up into multiple parts featured on different episodes. However, Nichijou episodes are ~three times longer.
The overall setting, feeling and humor is very similar, so If you like either of these, you'll love the other.
Dada-ist humour in a high school environment.
Over-the-top and episodic, both shows takes the boke in traditional manzai to new and absurd heights. Seki-kun is only a series of shorts, and as such you can almost see it fitting perfectly into the Nichijou school environment as just another skit.
Very similar style of comedy, over the top and fast paced. If you like Nichijou's pacing, absurdity, and humor, then this show is for you.
Both of these comedies work at the same pace, moving fast, but giving the audience enough time to get invested in the shenanigans and appreciate the execution. Both also work on the same magnitude, creating absurd, random scenes while maintaining a sense of cohesion, as if all of their events are happening within the set parameters of their own quirky little world.
Last, but not least, both have lovable, extremely expressive characters with great voice actors. What more could you ask for?
