Oh right. For the OPs of the original recommendations / “Zero Fanservice” shows:

• Promised Neverland: Orphans (IIRC, 12 years old or so at the start of the show?) discover that there’s dark secrets in their orphanage. They need to escape. www.youtube.com/watch?v=yB2t5y7ujlg

• Ranking of Kings: Bochi, the 1st Prince and 1st in line to the throne of the Kingdom of Bosse, is deaf, mute, and weak. The sickly Heroic King is worried about what will happen to the kingdom after he dies. The court (especially the Queen) is obviously favoring the stronger 2nd Prince. www.youtube.com/watch?v=s5SSAXK6bQE . Classic Fairytale feel and tropes (magic mirrors, emperor has no clothes, blood magic, deals with devils, magical stepmoms, shadow people, etc. etc.)

• Oddtaxi: Murder Mystery / Noir story with a twist. The protagonist is the Taxi Driver with damn good memory. The taxi rides of his customers largely have to do with the murder mystery and leads to the core of the murder. www.youtube.com/watch?v=jX-Ry1VxeDQ
