|Japanese Name||美琴 椿|
Tsubaki Mikoto (美琴 椿 Mikoto Tsubaki) is a supporting character in Puella Magi Suzune Magica. She only appears in flashbacks, but has a major impact regarding the events of the story.
- Age: Around 20
- Eye colour: Purple or violet
- Hair colour: Black
- Soul gem: Circular red gem on the back of her left hand
- Weapon: Katana
- Wish: "I want the power to defeat [witches]."
- Japanese pronoun: Watashi (私)
- Known relatives: Suzune Amano, her adopted daughter; she was also the surrogate mother for the Hinata twins. She had an aunt named Miyuki, who died sometime during the period when Suzune was living with Tsubaki.
Tsubaki took care of Suzune after the her parents' death at the hands of a witch, and treated her like her own daughter. She is also seen encouraging Matsuri to be a kind person and listen to her father and Kagari. She often told the Hinata twins stories.
Tsubaki only appears in the backstory of Suzune Magica, as she is dead before the story begins. Nothing is currently known about her past aside from Kyubey mentioning she was left alone in the world due to witches and that this caused her to use her powers for the first and last time to hurt another person.
Tsubaki was originally the caretaker for Matsuri and Kagari. She would often read to them the same bedtime story of a kind-hearted witch who was cast out of her village. After some time, she had to resign due to her having to care for Suzune who she first met after Suzune's parents were killed by a witch in front of her. She asks Matsuri to be a good girl and look out for Kagari and then leaves without saying goodbye.
After some time, she became a witch because she put Suzune's welfare before her own, always battling her hardest to keep Suzune safe and giving grief seeds to her first. Once she couldn't handle the state of her own corruption anymore, she transformed into a witch and was defeated by Suzune who absorbed her fire-elemental magic.
Tsubaki had fire-elemental powers. As Suzune absorbed her powers after her death, it can be assumed that Tsubaki had all the same spells that Suzune uses. Tsubaki is at least seen using one of Suzune's spells, "Flame Dance" (舞炎 Maien).
- Tsubaki's hairstyle is the same as the infamous "doomed anime mom" hairstyle, named because mothers with such a side-tie ponytail tended to die sometime in the story, usually early on or in the backstory.
- Tsubaki's appearance may have been reused from one of GAN's original characters, Sanae.
- Tsubaki's magical girl outfit has a rather "traditional" Japanese motif: the outfit itself resembles a kimono, and she wields a katana, a type of Japanese sword.
- Tsubaki having fire powers could reference how, back in the old days, people used to burn supposed witches at the stakes.
- Tsubaki's first name is spelled with the kanji for "camellia".
- Tsubaki is named after a flower, along with Matsuri and Kagari.
- In the Japanese language of flowers, camellia represent different things depending on the colour. They can represent love, perishing with grace, longing, and waiting.
- Camellia can also represent femininity, unpretentious grace, and unassuming elegance.
- Tsubaki's last name, Mikoto, is spelt with the kanji for "beautiful harp". "Mikoto" could also mean noble, precious, or revered.
- According to tweets by GAN:
- At first, GAN planned for Tsubaki to be someone roughly around Suzune's age who grew up in the same town as her. After some thought GAN wanted someone to act as guardian figure for the story, reworking Tsubaki to her current state. 
- A rather ambiguous tweet saying that "[Tsubaki's] appearance is just a hobby". This tweet might be referring to the art GAN did of Tsubaki in a maid outfit, but whether it is or isn't is unknown.
- Tsubaki's age is not clearly decided, but can be assumed to be around 20 or so.
