Bartender
|
Semi-anthologies with miracle working protagonists. The tones in both are pretty cool and collected, but Mushishi tries to look at the nature of all things, while Bartender has more insight into human nature and society specifically.

Kokou no Hito

Both protagonists tackle exactly what it means to be alone. Body horror art is also frequent in Homunculus and infrequent in The Climber.

Ultra Heaven
|
Utterly unfinished, and both have some of the most fascinating pseudo-horror art every chapter. The horror in Me and the Devil Blues deals more with emotion and expression, while Ultra Heaven is sheer hallucination insanity, but I still found myself engaged with them for similar reasons, somehow.

Fire Punch
|
Protagonists who are lost and don't know exactly what they're looking for, for different reasons. Both series have their takes on nihilism too, for better or worse.

The Fable
|
Hitman drama in both. The themes between these two almost couldn't be more different, and the tones they set aren't very similar either. Having said that, the concept of "hitman who has serious emotional problems" isn't exactly common. I also believe both series have amazing main antags, especially in the last half.

Holyland

Both series deep dive martial arts in their own ways, while also having showmen protagonists that develop their psyche as much as their skills.

Ajin
|
If you liked Ajin for Sato, then you'll most likely also like Ichi the Killer for Masao. Both are extremely compelling and entertaining antagonists that just love catching the reader off-guard. Be warned that Ichi the Killer is much a much more sexual series, while Ajin has none of that.

Imawa no Kuni no Alice

...then you might like
Tomodachi Game
|
Both series feature flashy games of life-or-death-or-debt, while showing off some themes of morality, ethics, revenge, and the value of a life.

Red

...then you might like
Golden Kamuy
|
Both are essentially spaghetti westerns with a focus on character development, while maintaining entertaining action sequences throughout.
If you liked
Mugen no Juunin

...then you might like
Golden Kamuy
|
While Blade of the Immortal holds on to more of a period drama setting and theme, it shares with Golden Kamuy a wide and compelling cast of characters set in historical Japan, as well as intense and gory fights.
