- The Kitaro Family Click to Expand
The Token Human in the 2018 incarnation of the Kitaro family, a human girl who rediscovered the legend of Kitaro and contacted him when yokai resurfaced in modern times, ultimately becoming a friend and ally.
- Accidental Murder: In Episode 47 of the 2018 series, Mana accidentally uses her new powers to kill Neko Musume after Nanashi tricked the latter into attacking Mana's mother.
- Ambiguously Gay: The way she constantly fawns over Neko Musume is suspiciously similar to a girl with a crush. In the Love Potion episode, Mana joins the guys in chasing after Neko Musume.
- Audience Surrogate: She serves as this at the start of the 2018 anime. The audience gets to meet Kitaro through her point of view.
- Beware the Nice Ones: After Nanashi faked her mother's death, her view on Yokais become distorted, and she threatens Kitaro with her spiritual powers after he arrived to rescue her.
- Big Sister Worship: She practically fangirls over "Neko-nee-san", saying she's strong, attractive and stylish. Mana even wore a costume based on Neko-Musume for Halloween.
- Break the Cutie: It starts when everyone around her suddenly view Yokai as monsters, then she witnesses Neko Musume attack her mother, unaware that Nanashi was responsible for it. She accidentally then kills Neko Musume and to tighten the knot, Nanashi made a vocal illusion to make it sound like her mother died, making her into a sobbing mess.
- Coincidence Magnet: Mana has a gift for being in the wrong place at the right time or having unexpected connections to a case; lampshaded by Medama-Oyaji.
- Designated Victim: She gets repeatedly targeted and captured by youkai. Kitaro and his friends almost always have to come in her aid. It rarely gets annoying though considering Mana is often able to help with her own escape in some way.
- Element #5: The seals Nanashi places on her are based on the five elements of Wu Xing: Fire, Wood, Earth, Metal and Water. It seems she gains powers based off of them. For example, she accidentally destroys a doll yokai and Neko Musume using a fire power.
- Fighting from the Inside: When she's briefly turned into a tanuki, her wish to save Kitaro lets her stay in control.
- Identical Granddaughter: She looks exactly like Nanashi's human mother, who apparently was a very distant ancestor of hers.
- Laser-Guided Amnesia: In the final episode of the 2018 series, Mana sacrifices all her memories of her youkai friends in order to resurrect Kitaro. She does remember Kitaro when they meet again several years later though and even plans to have a reunion with all her youkai friends at the youkai bathhouse.
- MayflyDecember Friendship: With the Kitaro family. As a regular human, Mana is surely to get outlived by them.
- Meaningful Name: Mana is written with the characters for "true name." Nanashi is finally freed from the mortal plane when she (a distant relative of his mother) gives him a name.
- New Rules as the Plot Demands: To make her useful in the miage-nyudo fight, the creators made it so that only humans could say "Miage-Nyudo, I've seen past you!" to deal with him. Meanwhile in the 1996 adaptation, Kitaro was able to do this by himself. They also left out the bit about the Miage-Nyudo having to respond to his name first.
- Nice Girl: A very kind and sweet girl, even willing to give Nezumi Otoko some bread with he was starving.
- The Not-Love Interest: She's the second girl closest to Kitaro in the 2018 anime and many of the episodes involve Kitaro rescuing her from evil youkai. Unlike Neko Musume, Mana doesn't show any interest in Kitaro that can be considered romantic and they truly view each other as nothing but good friends. In fact, it looks more like Mana has a crush on Neko Musume.
- Oblivious to Love: She never realized Nezumi Otoko and later Nurikabe were stalking her. Later, it never even passes through her mind that the human girl the tengu Kojiro likes is her.
- Painful Transformation: An excruciatingly one when she was cursed into turning a tanuki, with struggling through it to break the tanooki stone.
- Plucky Girl: Even though she's a normal human, Mana is very brave and won't hesitate to face anything to help humans in danger.

- Talking the Monster to Death: She ultimately defeats Nanashi by comforting him like the abandoned child that he is and giving him a name, as he always wanted.
- Token Human: The only, powerless, human being in a group of yokai.
- True Sight: She seems able to see yokai and transcendental beings, or gained this ability tagging along with the Kitaro family. This becomes less important as more humans regain their belief and are able to see yokai, but Mana remains more sensitive than most mortals to supernatural phenomena.

- You Killed My Mother: She temporarily loses herself in hatred after Nanashi tricks her into believing Neko Musume killed her mother.
