Kimetsu no Yaiba: Yuukaku-hen

Strong main characters with moral compasses guiding decisions Amazing animation Side character similar to Uzui Strong Female Leads Short watch Shamelessy Shonuen 

"Vanitas" has action and battle scenes. While "Demon Slayer: Entertainment District Arc" has better visuals and choreography, "Vanitas" has better dialogue and execution of humor (they have similar styles of comedy). 

Both have colorful visuals and non-stop, over-the-top action. 

both animes how a few similarities like: both anime have creatures which burn in sunlight and are based of vampires both anime have some type of breathing like hamon and demon slayer breath styles 

If you like high octane action series with godlike animation then you're probably gonna enjoy this 

EPIC VS fights. Face to Face yelling greatly focusing on clashing hits. Fight to the death/finish. Both sides NOT LEAVING "until I kill the enemy" 

Scarlet theme, good art, designs and fights, (Cool mask in Scarlet Nexus) and everyone got variety of attacks. Both Yuito and Tanjiro are driven to do right things, but they are newbies backed by a strong team/friends that help them so they don't fall to the enemy or to their own power. 

Both titles about prostitutes and samurai.
