This show starts out as a slice of life + girl in a wheel chair and then suddenly turns into a magical girls show... Being penned by Akame ga Kill's writer and heavily inspired by Madoka you can expect some suffering for these girls even though they complete their apparent goal with by Episode 5. The rushed approach is however not one I would consider good. After that episode the pacing is rather slow and there is little progression. The final episode (who doesn't have a writing credit by the original author) manages to invalidate all that has come before it and is worthy of the title "asspull".
If it wasn't for the suffering I would have dropped the show by Episode 6 and I would certainly not recommend the show to anyone. There are however people who champion this as an underdog so who knows ¯\_(ツ)_/¯.
