Chitose Get You!!

Anime in which characters have delusional personas, or believe they are a fictional character. Others may think they are out of touch with reality.

Chūnibyō (中二病) is a Japanese colloquial term typically used to describe early teens who have grandiose delusions, who desperately want to stand out, and who have convinced themselves that they have hidden knowledge or secret powers. It translates to "second year syndrome" (i.e., middle-school second-year), and has been called "eighth-grader syndrome" in English-speaking countries. [Wikipedia]

Made this interest stack to help locate 4-koma based anime for challenges and achievements more easily.

A Yonkoma (literally, "four-cell") Manga, better known as 4-Koma, is a short comic that consists of four panels arranged vertically from beginning to end, often adopting a plot structure known as "Kishotenketsu". Like western comic stripsnote , they are often found in newspapers, magazines, graphic novels, and other places. 4-Koma can be single-shot gags, or tell a story across several strips. (Notice that it isn't shikoma.) Expect nothing short of a Rapid-Fire Comedy from 4-Koma mangas, since they fire at least one joke every four frames.
