I’m a Little Earbud

The timeline includes: Ultraman Taiga the Movie + Tiga + Geed + Spy x Family + Ye Luoli + Douluo Dalu + I'm So Popular)

Bai Guangying is the fairy who represents light. During the war in the fairy realm, her former master lent her to the Queen. Unwilling to be enslaved, she fought back, and when she was sent to the human world, she became bound to a System. Later, she was badly injured while fighting the Ten Archons. The System took her to another spacetime, where she lost her memories and was reborn as Yun Jinshu, the little princess of the fox tribe. She was struck dead by the Heavenly Dao while undergoing her tribulation, then taken to the world of Ultraman. Read at your own risk: the female lead is a playgirl, not a self-sacrificing heroine, and this is not a traditional Ultraman story. It contains original worldbuilding. The male lead is undecided.

Daigu: “Guangying, you are the light. Go and do what you want.”

Tregear: “Little one, if you don't want me to lock you up, stay by my side.”

Hikari: “As my test subject, where else do you think you can go?”

Zero: “I like you the most, so don't you dare leave me.”

Mebius: “Guangying is my light.”

Cosmos: “I really want Guangying to see how unreasonable I can be.”

Belial: “Come fall into darkness with me.”

This story mainly takes place in the Ultraman world, with occasional cameos from other anime.
