In ep 1 at 19:58 & 20:46 there are references to Death Note such as the notebooks font and the way the book is opened.

Chiwa mentions she listens to the American band the Red Hot Chili Peppers at 15:31. This is probably another Death Note reference since their music was used in the live action movies.
