Current--- Naruto Shippuden - 204 ep(already i think,this is the best anime) Jujutsu Kaisen- 2 ep Recent finish- Tokyo Revengers -season -1 Naruto season 1
If I remember correctly, Death Note has no fanservice apart from some parts with Mia. And Naruto has the Sexy-no-Jutsu and a literal Ero-sennin. Otherwise, it's safe. It's actually hard to find shonen without fanservice. I think among the good ones with little fanservice are: Demon Slayer Attack on Titan Monster Rorouni Kenshin Trigun Unfortunately, addicts don't have it easy with manga and anime. Another reason to get rid of an addiction and gain the ability to read titles without worries about strong urges.
Bro, I'm a vetetan, watched Naruto from 2007-2014 when it ended and Death Note in 2009. Do you have anything else?
I've seen all those and dropped Rurouni Kenshin, but I haven't seen Trigun, I might have to add it to my list.
If Rorouni Kenshin was boring to you, you can try films. I've seen the first one and it was a wonderful adaptation with great choreography.
