A single song becomes a complete world. The animation moves at the speed of the music itself, never rushing, never settling, letting Shinji exist in a space where movement and stillness are the same thing. This is what comfort sounds like when it has a face. It doesn't ask you to feel anything except what the song already knows you need.
Susume! Shinji-kun is a one-episode music video set to the song of the same name, performed by Youko Seri. The piece was featured on Minna no Uta, a program broadcast by NHK. Viewers who enjoy short animation built around a single song may find it worth a look.
