Who are the cartoon characters "minister" and "school sister" that people often talk about?

In ACG's world, "senior" is usually used to refer to the role "Tomoe Mami" in the small circle of magical girls. This role shines brilliantly in the third episode of "The Little Circle of Magical Girls", which makes Xiao Yuan quickly upgraded to a god reserve. This work has set off an unprecedented discussion frenzy in the otaku world.

In addition, before The Witch's Circle appeared, seniors could usually refer to the heroine "Amano Tooko" in The Literary Girl. Even after Tomoe Mami became popular in the small circle of magical girls, you can occasionally see Amano Tooko being called "Senior Zi Yuan".

In Oriental Control, it is also useful for seniors to address luna's son in Oriental March Essence, because her hairstyle is very similar to Tomoe Mami's. Moreover, in the Warcraft fan map "DOTA Oriental Fantasia World", the production team specially changed the weapon to the musket like Tomoe Mami, and so did the trick. Therefore, this title is more common in the DOTA Oriental Fantasy Country game of Warcraft Oriental Fan Map.

At the same time, in the 20 12 popular new film "Accelerating the World", the heroine Kuroyuki hime is the student president of Xiangmei Middle School, one grade higher than the protagonist Arita Haruyuki, so Chun Xue has always called Kuroyuki hime "Senior Sister". Therefore, seniors can sometimes refer to Kuroyuki hime.
