Mitsuki Amanogawa

Mitsuki Amanogawa is a character from "Arifureta Shokugyō de Sekai Saikyō After Story".

She is Kouki's younger sister and the founder of the Soul Sisters.

Appearance
Mitsuki is a beautiful young woman with long glossy black hair and almond-shaped eyes.

Personality
Mitsuki is strong-willed and rambunctious. She is mischievous and would often pull pranks on those that she holds a grudge over, such as Hajime and Ryutarou. Just like Kouki, she is a spoiled brat for interrupting people's business only for her to be defeated for her insolence such as when she attempted to stop Hajime and Shizuku's wedding photo shoot along with the Soul Sisters, only to be bullied and humiliated by Hajime.

Just like her brother, Mitsuki is childish, deluded and a foolish idiot who's obsession for Shizuku borders on attraction for her. She believes Shizuku "belongs" to Kouki and have the "right" to marry her brother.

Biography
Mitsuki had known Shizuku Yaegashi since elementary school and was very fond of her. This eventually lead her to founding the Soul Sisters that was full of female students that also shared her fascination of Shizuku. Sadly for her, Shizuku and her brother Kouki, as well as their entire high school class, were summoned to the alternate world Tortus.

About a year after Shizuku and the other students returned to Japan, demon-worshipping cultists attacked the students, as well as anyone affiliated with them, including Kouki's family. They were able to keep the cultists at bay thanks to the barrier artifact that was provided to them by Shizuku's husband Hajime, but they still kept attacking their home. Mitsuki phoned Shizuku and asked for her help (as well as using the attack as an opportunity to see her again), but she was unable to come due to having to fend off cultists that were attacking her home as well. Mitsuki and her family were eventually saved by Kouki's best friend Ryutarou. Mitsuki then invited Ryutarou to the backyard in order to punish him for preventing Shizuku from visiting her due to his timely arrival. Ryutarou was aware of her intentions and fled her house as fast as possible.

When Shizuku and Hajime were on their way to do a wedding-themed photoshoot as a favor to Mitsuki's mother, they were suddenly approached by Mitsuki and the other Soul Sisters just as they arrived at the venue. They attempted to attack Hajime in order to make him unable to do the shoot. Hajime easily repelled the Soul Sisters after he grabbed one of them and forced her to drink a laxative before tying her pigtails up and writing on her face with a permanent marker as an example of what would happen if they tried to challenge him. As the Soul Sisters were prepared to leave, Mitsuki suspected that the student actually liked being bullied by Hajime, much to her denial.
