Joshikausei

Both are short Both have schoolgirls Both have off the wall stories 

its all about 3 high school girls that is a best friend 

both about a highschool female friend group<3 

High school life for the girls. Honestly nothing more than that. Both are cute and fun, although Wakaba is more focused on the former than Joshikausei is on the latter. Would recommend them for some fast TV shorts on the daily lives of anime girls. 

It may seem like an inane recommendation, but the unique presentation is something that merits this connection. Two sides of the sanity of high school girl comedy. Teekyuu being the insane side with fast pacing landing itself at the top of the hierarchy, compared to a quieter, zero dialogue, non-dialogue of Joshikausei. Both are fast and time-efficient comedy watches, so I see no reason to not watch the two. 

If one likes slice of life anime with girls, then this could be up your alley. Only difference is that the latter came out more than a decade plus ago. 

Both center around a cute high school girl who is kinda airhead and carefree, and always finds random ideas to have fun.  

High school life. It may not be the most eccentric, it may not be the most adventurous, but it is an honest experience, at least in Joshikausei and Aiura that is. Whilst they don't have a lot to offer other than the aforementioned, they are two high school stories you don't want to miss out on due to their simple and funny episodes. Both are comedic SoL shorts that are very fast to binge (both are TV shorts). With Joshikausei lacking dialogue and Aiura being a little true to aspirations people have.
