My top 5 uplifting anime list
1) Promised Neverland - Set in an orphanage where all the children play and help their guardian.
2) Made in Abyss - wholesome adventure with Riko and Reg as they explore a fantastic world to find Riko's mother and cure their friend Mitty from an illness.
3) Perfect Blue - fun idol based anime
4) Higurashi - Group of kids gather after school to play games and attend festivals
5) Berserk - An adventure anime with two best friends Guts and Griffith who set out on a quest for their king. Griffith can do nothing wrong.
Watched the video and while the list is pretty decent there's a few issues to mention.
