This is a beautiful animation. I didn't expect the animation to go the direction it did, but WOW, what a great way to take the story.
This is something that I think should be shared with everybody, to show that our bodies aren't terrifying.
I loved the characters. The teacher especially. I think he gave a nod not only to organ/body donors, but to educators, who often aren't given enough credit for their dedication.
Heartwarming, touching, brilliant. An overall phenomenal job. 5/5 stars, at least.
