~ Kaori's love for Hajime

Kaori Shirasaki (, Shirasaki Kaori?) is one of the main female protagonists from the "Arifureta Shokugyō de Sekai Saikyō" series.

She is one of the students from Japan involved in the Summoning Incident and ended up in Tortus along with her other classmates. She is the childhood friend of Shizuku Yaegashi, Ryutarou Sakagami & Kouki Amanogawa and was part of Kouki's party during the training in Orcus Labyrinth.

She had a long crush on Hajime Nagumo since she once saw him while she was in Middle School. Since her meeting, she admires Hajime's strong will. Realizing her love for Hajime after he fell into the abyss, she further pushed her resolve to become stronger in order to prevent it from ever happening again. After reuniting with him, she chose to join his party to win his heart and always be on his side.

She was murdered by Daisuke Hiyama and revived by Hajime by transferring her soul into stronger body. After Ehit's death and returned to Japan, she became one of Hajime's wives and returned to her original body after being modified by Hajime and made her as a hybrid Human and Apostle.


Kaori is your typical bishōjo (beautiful girl) with long black hair that reaches her waist and brown eyes. After she was killed, she uses the body of Noint, which grants her features of silver hair and blue eyes.


Kaori is your typical caring bishōjo, who cares deeply about her friends but most of all is her lover and later husband, Hajime Nagumo due to her love for him since middle school. She also has a strong will that allows her to overcome all obstacles. She is often told by the other girls in Hajime's party that she is a closet pervert for when she spoon fed Hajime with her spoon, and then quickly ate all the food with the used spoon. This side of Kaori appeared again when they were in the Haltina's Sea of Trees and she dreamed of being dominated by Hajime.

Kaori is often told she is very much an air-head and a troublemaker. She tends to say and do embarrassing things without thinking about her surroundings. This has always caused both Shizuku and Hajime a lot of trouble in the past because she failed to realize the attention she was getting. She has always been unaware of the fact that many boys around her have feelings for her and has broken many of their hearts without noticing due to her attentions to Hajme alone.

After witnessing Hajime fall to the abyss, Kaori becomes more focused and brave in her efforts to find him. She does, however, tend to overexert herself and not realize it at times. This did help her become stronger to the point where she was considered one of strongest members of the hero's party. Kousuke went as far as to say it was mostly thanks to Kaori that they survive their first encountered with Cattleya.

After joining Hajime's group and witnessing the other girls abilities, Kaori began developing a inferiority complex. Even through she was one of the strongest members of the hero's party, she could barely keep up with Hajime and the others, getting saved by Hajime multiple times in the process. Understanding this, Hajime offered to bring Kaori back to Shizuku if she couldn't take it anymore. However, Kaori decided to stay and refused to return to the Heilligh Kingdom after seeing how angry Hajime was when she was possessed and resolved not to let her weakness bother her anymore, but instead to become strong enough to stay by Hajime's side and will to do everything to ensure she win Hajime's heart no matter what it takes. This is further displayed after she was killed, where Kaori wanted Hajime to put her in a stronger body because she didn't want to stay weak anymore, even through she came to terms with her weakness. During the final trail of the Frost Cavern of Schnee, Kaori displayed how much she has grown to accept herself and her negative qualities, allowing her to gain the upper hand against her copy.

Kaori gets easily flustered or embarrassed whenever the topic of a conversation or any situation in general (usually involving Hajime) takes on a perverted or sexual nature.

Her desire to know more about Hajime's interests causes her to become an otaku after listening to his advice on what anime and manga she should check out. Even returning to Japan still has grown her.
