One of the reasons I do little research on a title before I watch it is to go in as blind as possible. Sometimes, this method delivers shocking results. I did not expect Rin: Daughters of Mnemosyne to be this graphic. And I’m not referring to the amount of violence and sex, but rather the manner in which the story executes these elements. Mnemosyne does not hold back when it comes to adult content. You have been warned.

Mnemosyne centres on Rin, an immortal woman fed a time fruit from the invisible tree Yggdrassil, who runs a private investigation agency alongside partner Mimi. Their job takes a turn when a search for a lost cat leads to amnesiac Koki and someone murdering these immortal women.

Most interesting in Mnemosyne is the structure, in that each episode takes place in a different decade. We start in the 90s and hop through the decades, seeing how society changes each instance, with the latter episodes set beyond our time and in the genre of science fiction. As such, the world building leaps forward each era – new global events in the background, technological advancements, aging mortals, etc. I particularly like how after a devastating earthquake, Tokyo’s depressed population retreats into a virtual reality of human indulgence. The people are so taken by the virtual that the real world is designated ‘Version 1.0’ – a launch version of the program, if you will. These are good world building details.

While the world evolves well across the years, I cannot say the same for the characters. Now, these characters aren’t bad, not at all. A core of the story is about how the immortal women don’t change while their mortal acquaintances die around them. Unfortunately, Rin and co. don’t react much to these changes. How much more interesting would it be to see a psychological toll for having such an existence? Or perhaps how they stay sane? Ironically, despite all the brutality, the story doesn’t push its characters far enough in the neglected psychological component.

The physical themes of sex and violence – two basic human instincts – have impact, certainly. The two sometimes (often) mix into some extreme form of BDSM – torture, mutilation, eroticism, bits missing, naked bodies, the full monty. The blood angels hunting Rin lure immortal women with the human instinct of lust, granting a state of ecstasy before devouring them. Mnemosyne is bold with its sexuality and not ashamed of it. Interestingly, none of this is gratuitous. Yes, they could have cut away before the graphic material starts and dropped down to a lower age rating tier, but the violence and sex drive the plot and characters of this supernatural world. These elements and the plot type give this anime a vampire fiction-esque feel.

Mnemosyne’s story problems lie in the first act of most episodes. The writing needs work in linking Rin with the key character introduced each episode. For example, in the first episode, after leaving the scene of a truck accident, she runs into Koki and helps, responds, and acts towards this stranger as though he’s a close friend. Her actions aren’t believable – nor is his response. The writers needed to get these two together and didn’t think of a proper way to do it. This happens consistently. Funny enough, each episode consistently improves in the same way after the first act as well. Flawed, but consistent. How odd.

Rin: Daughters of Mnemosyne is so close to being great. Its good points have strength, but the weak parts are significant enough to hold it back. The characters needed that extra emotional push, and a main villain with more presence than minor antagonists would have assuredly helped. Even so, this anime engaged me to the end.

Art – Medium

The art is good – strong imagery – but could do with more animation and a touch more gothic. And get rid of the Photoshop filter used in flashbacks – looks cheap.

Sound – High

Mnemosyne has great acting in both versions and music that evolves with the times.

Story – Medium

In a world of sex and violence, the immortal Rin investigates attacks against her fellow immortal women through the ages. While engaging (and brutal), Rin: Daughters of Mnemosyne doesn’t give the emotional side enough focus to match the physical.

Overall Quality – Medium

Recommendation: Try it. Rin: Daughters of Mnemosyne is hard to find an audience for with the extreme sadism, but if you don’t mind that, it’s worth a try. Give it two episodes at least.

  1. I was pretty caught off guard by the content as well but I liked how they used it to propel the story forward rather than insert random sex scenes for the hell of it. I agree than they could have worked better to invoke a more emotional connection to the characters.
