Based solely on this ID and the language style of these two answers, Xiang Kun has constructed an image of a goofy girl in his mind.
He continued reading "August's Kasumi's" updates. Besides the two answers, she also followed several other questions such as "Is Raw Meat Tasty??", "What Parasites Are in Blood??", "What are the differences between the components of human blood and those of other animals?", and "What Is Bloodlust Disorder??".
But all of these events occurred two days ago.
However, this account isn't new. Going back further, there are posts from five years ago, but back then the posts were mostly likes on answers related to anime and cosplay, a completely different style from now.
There is very little information to be gleaned from these updates alone.
Xiang Kun copied the answerer's ID to several search engines and searched for it. Apart from Zhihu, he did not find the same ID on any other platform.
Everyone has different habits when creating online IDs. Some people like to use the same ID consistently, while others just pick one that works on a whim.
Regardless of the method, unless it's intentional, the chosen ID will more or less be related to the person's subjective intentions.
The word "Kasumi" is a Japanese romaji. Xiang Kun found out after searching that it has many translations as a name, such as Kasumi, Kasumi, Kasumi, Kasumi, Kasumi, Kasumi, Kasumi, Kasumi, Kasumi, etc. It should be said that it is a relatively common name. For example, there is a Japanese actress whom Xiang Kun knows, Kasumi Murakamura, whose name is also kasumi in romaji.
Judging from the types of questions this user followed when they first Zhihu five years ago, Kasumi is most likely the name of a Japanese anime character.
The search results show that there are many anime or game characters named Kasumi, such as Kasumi from Pokémon, Kasumi from the Dead or Alive series, and Kasumi Tendo from Ranma 1/2.
However, none of the anime mentioned in the answers that the respondent followed five years ago contained a character named Kasumi, so it's difficult to determine where Kasumi came from.
Or perhaps her Chinese name is something like Xia.
As for August, it could be that her birthday is in August, or it could be that she registered in August.
The image recognition function identified the respondent's profile picture as Misaka Mikoto from A Certain Scientific Railgun.
The name of this character was also a topic she was interested in five years ago.
Xiang Kun has already listed in a table the anime and anime characters that "August's Kasumi" has mentioned in the answers and questions he has followed, as well as the avatars, but these alone are still not enough.
"There's still too little information..." Xiang Kun scratched his head.
If we could directly access Zhihu's backend and see her registered email address, phone number, and other real-name information, it would be much simpler.
However, that's almost impossible.
Hacking into Zhihu's backend? Xiang Kun says, "I could never do that!"
His gaze continued to sweep across the Zhihu page, clicking into the six people she followed. After checking, he found that they were answerers specializing in anime, and two of them had been reset. Her two followers, on the other hand, were both banned accounts, clearly advertising or something similar.
Xiang Kun continued to look at the questions he was following and the answers he had liked in his feed.
Then she went through the comments on all the answers she had liked, and found one of her comments in an answer she had liked five years ago.
The person who answered that question posted a photo of themselves cosplaying a female anime character, and "August's Kasumi" replied in the comments, "Wow! ヾ() So cool! I have this outfit too, but why doesn't it look the same on me!!! 555555!!!"
This is the only post left by the account "August's Kasumi" besides the two replies from two days ago.
This reply shows that she also does cosplay, at least five years ago, and that she also had this outfit.
Search for users with the same profile picture or posts mentioning the same character cosplay in the relevant anime/anime character forums, Douban groups, and related communities.
While pondering the search rules, Xiang Kun saved the cosplay photo of the respondent in the answer she had replied to, and then used image recognition to search for it.
Searching through the results one by one, Xiang Kun suddenly found a post on a niche anime forum. The poster had posted the same photo in the main post, then followed it with a photo of the face covered, and a crying emoji.
"555555!!! Look at this, what a difference between a seller's photo and a buyer's photo! Their cosplay and mine!! Same cosplay, same character, same outfit, how come the difference is so huge!"
The row of 5s and exclamation marks immediately caught Xiang Kun's attention.
Then he started searching for all the main posts and replies of this account called "Full-Time Magical Girl L", and found many emoticons, including the "ヾ()" emoticon, which had also been used in comments on Zhihu and appeared repeatedly.
Although there is no very direct evidence yet, Xiang Kun has already convinced himself, based on his intuition, that this is "August's Kasumi".
She posted far more on that forum than on Zhihu. Not only did we find the QQ email address she posted asking for resources, but we also learned that her birthday is August 11th—she herself said on August 11th of a certain year that today is her birthday.
Continuing the search, I learned that she lived in a certain city and that she was in the second year of junior high school five years ago.
Then, relying on this information, I found her Weibo. From the watermark "@kasumiiii" on a photo from a few years ago, I knew that her ID name contained the keyword "kasumi", which further confirmed that she was "August's Kasumi".
Scrolling through her Weibo, I found her selfies; she looked like a youthful and sunny girl.
I found her school name from some pictures, and from her interactions with other people, I learned that her real name is Lü Xiaoxia and that she is in a certain class.
Xiang Kun then found her Baidu Tieba account, her Bilibili account, her Douban account, and even another Zhihu account.
More importantly, although she herself doesn't post on Weibo very often, with her latest post being a week ago, her classmates who follow each other and frequently tag each other posted photos on Weibo of a group of girls going out for dessert during the National Day holiday the day before yesterday.
In the photo, a dessert is also placed in front of the smiling "Lü Xiaoxia".
If she was already a vampire at that time, how could she chat and laugh with her classmates while eating in a dessert shop? She also found a method similar to Xiang Kun's to make normal food stay in the stomach longer? But with the desserts they ate that were mostly liquid, even if Xiang Kun swallowed two pebbles that established a connection, it wouldn't be able to suppress them at all.
Xiang Kun looked at the activity pages of the two Zhihu accounts he had placed on the left and right of him on the screen: "August's Kasumi" and "Dawn Glow." They were both accounts belonging to a high school girl named Lü Xiaoxia. The former was from five years ago, while the latter was the one she had been using frequently in recent years.
