What is the ruling on following the anime "Attack on Titan," which features naked giants eating humans and characters who transform between humans and giants?

The aforementioned anime does not show anything that necessitates its prohibition. The guidelines for watching cartoon films can be reviewed in Fatwa no. 138197. A believer should utilize their time in what benefits them in their religion and worldly life, for a Muslim will be held accountable for their time on the Day of Judgment, as stated in the Hadith: "The feet of a servant will not move on the Day of Judgment until he is questioned about his life – how he spent it." Wasting time is one of the punishments for sins, as mentioned by Ibn Al-Qayyim.
