Aiura in a nutshell is 4koma manga about 3 girls and their daily school life.From the outset it does seem a pretty generic slice of life 4koma but as the saying goes sometimes cliches are the best and its better to have cliches than something unexpected.
Story 7/10
The story is pretty simple and there is no major plot to deal with here just a manga like this should be.
Art 7/10
Art is simple nothing particular to state besides that it is good on the eyes and not over bearing.
Character 8/10
This is where the manga excels and the true enjoyment comes out of.Besides the 3 there are other set of characters being their friends and teaches who are really likeable in this manga.They are as cute as the main characters and will make to laugh out with their antics.
Overall 7/10
Though aiura doesnt bring anything new to the table it does give you the nice vibes that these manga should generally provide.If you want to sit back,relax and read about daily shenanigans of a set of high school girls then go for this.
