What عملی حکمت would آپ دکھائیں a 20 سال old guy who has never watched عملی حکمت before?
In my opinion I think a good starter عملی حکمت for a 20 سال old guy would either be One Piece یا Naruto. A mainstream عملی حکمت that doesn't have too much gore یا fan-service to tell them that عملی حکمت isn't only about that.
Try to دکھائیں him an عملی حکمت that tailors to his preferences. Like i.e if he likes comedy alot. دکھائیں him a comedy anime. یا action and such and such. If I am trying to introduce someone into anything. I'll use what I know of them to find the best thing to introduce them to.
Technically no gore, as it takes place in a video game, but Sword Art Online. Naruto is a good choice, too. An عملی حکمت I just started watching is Your Lie in April, and I'm in love with it. Pun half-intended. Just don't watch Your Lie in April if آپ don't think he'd want to watch a story of an 8 grade boy and his دوستوں in a small love triangle. (I'm only on the 10th episode, so maybe it's about مزید then an ex-piano prodigy and the girl he likes and the girl who likes him.)
Even though Lucky سٹار, ستارہ was my gateway anime, I cannot recommend it as a first anime. However, I can recommend Working!!. It's funny and cute, and I enjoyed it since I was 13. (12 if آپ count me listening to the opening over and over again)
