Rapparu is an 18 year old animator from Tokyo who appears to have more raw talent than most teens and some adults. The first piece is called Tenkou Kotofumi according to Crunchyroll (I can’t read the kanji and confirm that). The only part of the animation he didn’t build himself was the music, he got that as a free download song from Trial and Error. He has also created a ton of amazing black and white line art animated GIFs, and he compiled some of them into the second video on this page. I haven’t found anything of his that tells an entire story yet (or at least not one with dialog), but I am looking forward to seeing what else he comes up with.
