Tari tari is Yuri anime, togetoge is shounen manga.

Thank you for the question and for your curiosity regarding the relationship between TariTari and TogeToge. While at first glance the titles may evoke a sense of similarity due to their rhythmic structure and use of repetition, these two series are, in fact, not directly related in terms of plot, characters, or production. However, I can see how such an inquiry arises, as anime titles often share thematic or stylistic elements that create these associations.

TariTari is a slice-of-life anime produced by P.A. Works, airing in 2012. It centers around a group of high school students who form a choir club and experience the emotional and personal growth typical of the genre. Music plays a pivotal role, and the series delves into the everyday lives of the characters as they navigate the transitional period of adolescence, friendship, and the pursuit of their dreams. TariTari is particularly known for its heartfelt tone, stunning animation, and character-driven narrative—a hallmark of P.A. Works' school-themed projects.

On the other hand, TogeToge (if you are referring to the title in the same medium) is not a widely recognized or mainstream series, and without further context or more information, it is difficult to ascertain the exact nature of the title. If it exists, it could either be a lesser-known or more recent anime or manga, perhaps more niche or experimental in style, or a fan creation not widely distributed. Alternatively, you could be referring to an unrelated work in a different genre or medium entirely. If this is the case, it would be helpful to specify, as the landscape of anime and manga is vast and filled with many smaller, independent projects that might not be on the radar of the mainstream community.

That being said, to the best of my knowledge, there is no shared universe, crossover, or official linkage between TariTari and any series titled TogeToge. The similarity in their names appears to be coincidental rather than intentional. If TogeToge is an original creation or a recent release, it might be interesting to delve deeper into it, and I would encourage you to explore both titles individually to appreciate their unique storytelling approaches.

Should you come across more details regarding TogeToge, feel free to share, as I would be happy to investigate further and update the community on any potential connections or thematic similarities that may have gone unnoticed.

Cheers,
