The three new school groups of characters does originates from the mobile game and for the first few episodes they bring them into context though their leaders gets more screentime like Akira Yukishiro, Aruru Otsuki and Tamao Tomoe. All three schools have their strengths in a center area of the arts, like Siegfeld being focused on being the "elite" of the elite focusing on many arts, Frontier Arts being more into their Western and being carefree and Rinmeikan in tradition Japanese and being calm and collected, though the characters originating from them and considering it's a comedy anime short are obviously unlike the schools focus though with this large of a cast and the short solely focused on quick one-liners and some character jabbing, hey world building isn't exactly in this anime short's focus, though it shows in the schools intermingling with one another as well as character interactions in general.
The comedy through this excels in it's quick one-liner jokes on the huge cast of characters which helps get to know the new characters (and for people who play the mobile game, a bit of fanservice LA supposes) and yeah the comedy is good as LA did chuckle a couple of times and due to the short runtime in general it makes it even better making all the one liners and jokes snap. Latter on the comedy is more to do with one joke taken to the extreme in some extent, this can land or miss most of the time. To this end, Shoujo☆Conto All Starlight latter becomes nothing but isolated episodes looking at the different three new groups sometimes mixing with Seisho Music Academy girls in some vocal and visual hijinks.
The animation done once again by Kinema Citrus and the new studio entering the stage, Imagica Lab, well the animation is minimalistic to say the least background and the chibi characters but the chibi character designs reminds LA of those chibi acrylic prints of anime character you see but animated. The background isn't much to talk about but still works with the chibi character designs anyways. It's chibi comedy anime short and though Shoujo Conto All Starlight does do the rare weird stuff, it's mostly chibi characters on ok backgrounds.
The voice cast, due to THREE new school groups entering the stage makes this voice cast IMMENSE, but LA will just say the voice cast fitted well with their respective roles, especially Hotaru Nomoto as Akira and Megumi Han as Aruru. One thing LA did note is that in the latter episodes, it seems that the majority of the voice cast go almost ad-lib in their reactions and it shows in their laughter.
Shoujo☆Conto All Starlight gives a comedic twist to the Revue Starlight world whilst adding in a bunch of new characters in the process and giving us what other schools Revues and training for it is like, but mostly chibi comedic hijinks with Revue Starlight, if you are fan of Revue Starlight and want to see a more comedic take on it with new characters at that, then Shoujo☆Conto All Starlightt is for you!...well that and if you played the mobile game of course.
