Gintama, Tonari no Seki-kun Recommendations
The over-the-top execution of an absurd situation is carried out the extreme in both Tonari and Gintama. The Tonari manga has better artwork.
Do you like Katsuras dreams and delusions like where a simple count of leap of a sheep in mind he had to fall asleep, turns into a heartwrenching storytelling of a young ladys leap of faith. Well, if you enjoy insane troll logic for fun you might like to watch Tonari no Seki-kun, though the whole show is a running gag in a skit format.
How are they similar? Both are very creative and funny! Both show are mainly random and are just to make you laugh. At times, Gintama has some serious time which is awesome! If you like randomness and comedy, you will just love both of these anime.
