Yan, no surname, single name Yan, male, age 10,000+.
Please don't get me wrong, he is not an immortal monster, he just keeps traveling through time.
As soon as he dies, he will be resurrected in another world - so his age is 10,000+.
The disadvantage is probably that I live so long that I get a weird disease: Facial Recognition Disorder.
In layman's terms, it's face blindness.
To put it more plainly, disciple L came to see him yesterday, but he thought he was disciple Z who had been dead for more than ten years.
So Yan feels that his biggest problem now is that he is Mao's teacher, but he can't always remember who his students/friends/people he knows are Orz
For example——
Urahara Kisuke: "Yan-kun, long time no see."
Yan: "Uncle, who are you?"
Urahara Kisuke: "..."
Captain Ukitake Jushiro of the Thirteenth Division: "Will Yan Sang join our Thirteenth Division after graduation?"
Yan: "Oh! Aren't you Unohana Shunsui, the captain of the 10th division?"
Ukitake Jūshirō: "... No, I am the captain of the 13th Division, Ukitake Jūshirō. Yan-san, you will also be joining the Gotei 13th Division in the future. At least remember the names of the captains of each team."
Yan: "Okay."
Yan was speechless about this. The members of the Gotei Thirteenth Division were all pretenders, even if the captains were wearing feathers. No wonder he would admit his mistake, right? Even if they had hair colors as colorful as a palette, he couldn't clearly identify the person he knew.
So who are you, that person over there with a very fake smile and black-rimmed glasses?
Aizen Sosuke: "..."
The host is 1v1, CP Aizen Sosuke.
The protagonist has traveled through time, but he has lived too long to remember any of the plot, but he still has a vague impression.
