I love my fair share of mature stories, specially if they have a samurai going on a journey for whatever reason it is, but this one was actually a very cheap shoujo desguised as a mature cast show.
That because: Unlike what the title suggests or even the synopsis hints at, Manji (the Immortal) isn't actually the main character. He is not even a secondary main character at that, since his only purpose in the story is to serve and protect Rin because of his sob backstory of having his lil sister killed so now he needs a proxy young girl to make up for it. Supposedly he has a new personal goal of "killing 100 criminals" to make up for the 100 people he killed as well, but he throws that away quite quickly as Rin randomly asks him to kill random normal men in order to protect the guy who killed her parents... Yep. That also happens.
Once you push the actual samurai AND mature character of the story so much to the background he becomes just a simple plot device, what's left is the 16 year old girl who can't seem to do even the very basics at self defense despite presenting herself proudly as a dojo master's daughter time and time again. Rin has a very simple drive force and goal, which is to avenge her parents cruel deaths but for some reason along the line the story botches even that very simple train of thought as she goes on to pretect and care for her malefactors for reasons completely unknown.
I know some people can argue that is supposed to make her relationship with the villains complex and unique, but the execution is very nonsensical. I'll give you an example: At some point, she orders Manji to kill a group of men trying to kill Anotsu (the guy who ordered her parents murders) because he did to them the same as HE did to her. And she argues that he is sick >>>>>.<<<<< so you know? It's kind of unfair to fight a sick person!!!!! So then nothing more fair than killing a bunch of other victims like yourself TO PROTECTED A GUY YOU YOURSELF ARE TRYING TO KILL!!!!! There's even more nonsensical stuff, like when another immortal samurai appears, and he's very bitter and tired of immortality and goes on and on about seeing people he loves die before him and all that shit, and how he became kind of a sociopath because of that BUT!!!!! HE CARRIED WITH HIM A POISON THAT CAN ACTUALLY KILL HIM LMAOOOOO like?????????????? And then he """"chooses"""" to let himself be killed by Manji and Rin because he is tired??????????? BUT HE COULD'VE DIED LITERALLY ANY MOMENT HE WANTED TO LAKSLKASDJLKS I'm sorry, at some point I just couldn't take this bullshit anymore.
