Katsugeki/Touken Ranbu

Both have male MC's Both have same alure and story, to keep history and keep novel's alure straight. Fight for nuisance creature.  

mythological figures get summoned to modern era to deal with demonic creatures threatening human world. the mission gets really personal midway, and the characters are left with no choice but to face ghosts of their own tragic past. 

Another Anime version of Touken Ranbu, albeit set in a different continuity. If you like action-oriented Anime or just want to see the characters you liked here in a different setting, it’s for you. 

Both are action series animated by Ufotable focused on samurais in Japan's past. While Kimetsu no Yaiba touches only the Taisho period, Touken Ranbu goes back and forth between the Heian, Edo and Bakumatsu periods. 

both anime use past heroes as characters in their anime, but instead of using hero spirits, Touken Ranbu uses the character's weapons as characters. and both anime tell the same story to protect history that is in trouble 

Although Katsugeki/Touken Ranbu is a Japanese anime unlike Mo Dao Zu Shi being Chinese, they both have a similar artstyle (with MDZS definitely being superior with its beautiful art while still keeping the resemblance), both stories happen in the past, talk about Samurais, show off mysterious creatures filled with negative energy and people fighting against them. The characters are also pretty comparable at some points, most of them being long-haired man wearing Chinese-ish clothing, yielding their swords and fighting evil. In my opinion these two anime series give off a very similar vibe, both the story and the overall look. 

In both anime series the MC are sent back in history in order to protect something . The only difference is that in drifters there are many other creatures like Elfs , dwarfs and others. In Katsugeki/Touken Ranbu the MC are animated swords that must protect the history and in Drifters they are warrios from different eras of Toyohisa's world who were thought to be dead. 

Swords, boys, light beams, intense action choreography, Japanese history, and both are based on games... these two shows are surprisingly similar. Sengoku Basara has a brighter palette and a more positive feel, whereas Katsugeki is much darker. Outstanding action in both shows, Katsugeki being the more polished of the two with very good utilisation of CG. Neither are exactly shows to watch for plot or character depth, but if you're a fan of the games or are looking for some fast paced shiny action fuelled by shouting, give Basara or Katsugeki a try. 

Both have elements of the Shinsengumi, But Touken Ranbu is about historical swords transformed into men to protect history. The swords from the shinsengumi include Izuminokami Kanesada(uchigatana) and Horikawa Kunihiro(wakizashi) wielded by Hijikata Toshizou 

Do you like historical/battle action shows with AWESOME sword fights? The main difference between the shows is that the world in Token Ranbu definitely has a touch of fantasy whereas Rurouni Kenshin has a realistic setting but if you like well choreographed fights and shows set in historical japan than give these series a try. 

If you love slightly gay bishounen swimming then you're gonna love slightly gay bishounen samurais saving the history. 

Two shows that seem like b-rated (fairly unique) plots, but are pretty intricate and relevant. Main characters fight to prevent some atrocities that keep happening. Pretty boys, inanimate objects holding real value, pretty similar overall
