Got to watch it in Fantasia 2019!
Riding a Wave with You is a touching story on how people live life, drawing some power from visual metaphors along the way.
I personally have watched too much anime, that I can no longer pick up new series without readily detecting the writing patterns the last 10 or so years have tired me with.
Riding a Wave with You, however, breaks away from all these writing weaknesses, and offers you a fresh new story, devoid of today's mainstream anime drivel.
It is a good pick to watch if you can, so I would highly recommend it!
