Hello!
I want to solve different contests to learn a new language (Kotlin), but I have a busy shedule (and cannot write regular contests in suitable time), so the only way for me is to train using virtual contests.
There is a great variety of contests on Codeforces (thanks to Mike!) and consequently it is not easy to decide which contests to solve.
I love random, but I have a better idea. Let's make the list of anime-themed contests!
But I need your help (in comments) to find them all...

List of anime-themed contests (the list is updating):
