Yes, Demon Slayer features a very brief kissing scene.
A Quick Look at Romance in Demon Slayer
While Demon Slayer is primarily an action-packed anime focusing on Tanjiro's quest to save his sister and defeat demons, a small amount of romance is present. The anime includes one short instance of a kiss, lasting only a fraction of a second. This scene involves two minor parental characters. It's important to note that this is a very fleeting moment, and the show doesn't focus on romantic relationships.
While not directly related to kissing, it's worth mentioning that some female characters have revealing outfits, particularly a female demon in the Red Light District Arc who wears a skimpy bikini-style outfit during fights. However, the show avoids excessive fan service and keeps such instances relatively minor.
- Key takeaway: The kissing scene is minimal and insignificant to the overall plot.
