The titular character, Reiri, grows and develops greatly throughout the unfolding events, slowly changing her view on existence and life, and despite the bitter sweet ending - it fits her growth, and mirrors her origins well.
Difficult to put down, beautifully illustrated, and masterfully paced - Reiri is evidently a work of great skill and effort.
Art - Beautiful and refined. A blend of realistic and stylized, with aspects of it feeling gritty and tangible, at times horrifying, and others feeling light and distilled to the essence, it's one of the prettier mangas out there.
Story - An interesting story that keeps you glued to the pages, wanting to find out what happens next. A mix of personal character growth and broader historically inspired intrigue, it is well paced, and focuses on just the right scale to make everything completely engrossing at all times.
Writing - From dialogues to the progression of the story, everything is great.
Characters - A strong point of Reiri is the characters in it. They are of equally great quality as all other components of this manga, and turn the experience of reading it into one of the more immersive historically inspired reading experiences out there.
If only there was an official English release as well, since there's nothing I'd want more than to own the entire physical set of this.
