Tantei gakuen q anime

[Claraviolet]

I have watched it. It's a long anime and the cases were pretty predictable and the animation is really old too. Still, I don't really regret watching it. I just hoped a bit more mystery would be present but...alas...it's a normal detective anime.
Anyone watched it here?

i heard that the cases are closed door cases and are quite difficult to solve. it's in my watchlist but i never got around to watching it. i will be watching it
