I'm not sure specifically what 'tg tf animation story' is about without more context. It could be a transformation-themed animation story, perhaps involving characters changing in some way like shape, form or identity in a fictional animated world.
Definitely. Popular girl TF TG stories on DeviantArt may often have elements that resonate with a wide audience. A story that combines TF and TG in a way that tells a story of empowerment for the girl character could be very popular. For instance, a girl who is transformed into a stronger form (TF) which also changes her gender (TG) and she uses this new form to overcome challenges in a fantasy world. These types of stories with strong themes and interesting characters can gain a lot of popularity on the platform.
One well - known story is about the 'Haunted Manor'. There was a girl who was said to be possessed by a ghost in that old manor. People claimed to see her transform into a different form, with strange behavior. She would sometimes speak in a voice that wasn't her own and seemed to have knowledge of things that happened long ago.
In one story, a girl was showing signs of possession by a ghost girl. But it turned out that the ghost girl was a former occupant of the house who died unhappily. The family living in the house worked with a psychic to communicate with the ghost girl. They fulfilled her last wishes which were simple, like having a proper burial place remembered. After that, the possession ended and the girl was fine, and the house no longer had any spooky vibes.
One example of a somewhat similar story could be 'Fairy Tail'. In this anime, some characters have the ability to transform in a sense, like Natsu can enter a more powerful form. Although it may not be exactly the same as 'tg tf animation story', it has elements of character evolution and change during combat or in certain situations.
There was a bunny girl. She came across a strange potion. After drinking it, she experienced a tf (transformation). Her bunny ears became longer and fluffier, and her body became more agile. As for tg (transformation guide), she learned from an old rabbit in the forest. The old rabbit told her that this transformation was a sign of her growing into a more powerful bunny girl, and she should use her new abilities to protect the forest.
Another plot could be a reincarnation - based story. A girl dies and is reincarnated as a boy. She retains some of her memories from her previous life as a girl. In this new life as a boy, she has to navigate a different world, different relationships, and come to terms with her new identity. This type of story can be really interesting as it combines elements of the supernatural and the exploration of gender roles.
A cat girl named Luna once found a magical pendant. When she put it on, she underwent a tg (transformation gender) tf (transformation form). She changed from a cute cat girl to a more human - like boy with cat - like features. It was a strange but exciting experience for her as she had to adapt to this new form and the different reactions from the people around her.
A bunny girl lived in a bustling city. One day, she was exposed to a strange energy wave that caused a tf. She became a bunny girl with mechanical enhancements. For the tg, she met a tech - savvy inventor. The inventor explained that she was chosen for this transformation to fight against a new type of crime in the city. So, she used her enhanced strength and speed, along with her cute bunny charm, to keep the city safe.
If 'tg tf' means 'tiny gifts, tall fun', on her birthday, the girl could receive some small but very meaningful gifts from her friends and family. These gifts might not be expensive but are full of love. And then she has a lot of 'tall fun'. For example, she goes to an amusement park and rides the tallest roller coaster. She has a great time, screaming with joy and feeling alive on her special day.
