Recently, a new donghua (Chinese anime) called All Saints Street (万圣街) was adapted.
The opening, also named All Saints Street, features the Vocaloids: Luo Tianyi, YANHE, Yuezheng Ling, and Mo Qingxian, and was tuned by Creuzer, who is basically the cillia of bilibili.
I highly recommend watching the donghua. The first season (12 episodes) is out with each episode approximately 3 minutes long.
