Yu-Gi-Oh!
A lot of (attempted) murder, but still has the vibe of being kid friendly since most things are won by the power of friendship. Treats female characters in a very shounen way lol

Summary: High schooler Mei-chan desperately wants a boyfriend. Suddenly, an ikeman from her school asks her out and wants to be her love! But in fact, this guy is sort of ... softcore yandere? Review: He says really yandere things (and seems to have a sort of cannibal/carnal fetish lol), but they haven't even kissed. So far, scenes have been suggestive, but I don't think it will ever be explicit. The female lead can be dumb but also wise with an understanding of healthy relationship actions. It feels like the mangaka is a feminist who also loves the yandere and school romance genre.
