D-frag is a recommended comedy with a good flow on its' story, the best of the best. That's a good taste
Good night Mirall
It's a bit hard to know what are you referencing about with the title. While it is mostly used as a farewell in a way, realization, grief, or Carmine with baby Mirall.
There's the Maoujou de oyasumi about the sleepy princess which is a comedic and as good like D-frag, in my own opinion.
P.S - I shall look forward for the next game.
