"Monogatari Series" by Mayoi Hachikuji

Mayoi Hachikuji is a character in Nisio Isin's light novel series 'Monogatari' and its derivative works. She looks like a polite elementary school student around 10 years old, with black twin ponytails and red eyes, carrying a large hiking backpack, and often wearing band-aids on her knees. Its true identity is a ghost that has wandered in the wandering of the Lost Path for 11 years, and is the true identity of the strange "Lost Cow." When her parents divorced in third grade, she was adopted by her father and changed her surname to "Bajiusi." At age 10, on Mother's Day, unable to remember her mother's face, she secretly visited her mother but died in a car accident on the way. She has the trait that only those who don't want to go home can see her, causing those who come into contact to get lost. She often mispronounces Koyomi Araragi's name and teases each other about liking Koyomi Araragi. With the help of Koku and others, she once reached her destination and escaped the Lost Ox, but later, for violating strange paths, she was hunted by the "Shadow of Darkness" and ultimately passed away with a smile. However, she later falls into hell and is brought back to the mortal world by Koyomi in 'Finals (Part 2)', where she is worshipped as the deity of the Kita Shiraja Shrine. In the alternate world of "Qing Monogata," she is a smart and strong adult woman around twenty years old.
