Lin

On the Internet exists a pretty popular content creator who teaches others how to make bentos for one. Not only does her weekly tutorials include well-thought-out pairings and aesthetically appealing presentations, but her tone of voice is also always upbeat and adorable, earning her many fans. However, what people don't realize is the multiple other identities this adorable content creator has, such as a blogger who talks about cute accessories and a devoted fan of a particular romance comic...
It's already hard for anyone to connect the dots that these seemingly unrelated accounts are all run by one person, never mind figure out that this girl, who's known to be vibrant and adorable in the online world is, in fact, someone who does covert work for Night Chains in real life. Likewise, people who know Lin in real life will 100% be baffled if they learn that she has such a lively personality online.
To Lin, it will be a disaster if anyone who knows her in real life discovers her online identities, which is why she often becomes flustered whenever someone praises her for her fast typing speed, as she fears she may inadvertently give herself away.
That said... if it's someone she's close to, Lin tends to secretly hope they will find out and admire her charm and yet also worries that such a stark contrast will cause them to view her differently. This dilemma has plagued her, persisting even to this day.

Lin was an extremely ordinary student in school and an extremely ordinary daughter at home. Yet, she was constantly reprimanded for this ordinariness. Although her parents' positions in the CoC weren't high, they did cross paths with people of different statuses over work matters, and this expansion of horizons kindled the yearning for a better future. Sadly, the best that the couple could do was probably just as employees of the CoC, which was why they placed all their hopes of moving up the social ladder onto their only daughter.
They kept wishing that their daughter could become more outstanding and distinguished. If Lin did not reach the standards they had for her, it meant that she must not have tried hard enough. Lin truly couldn't please her demanding parents with her limited capabilities and always had to hear them criticize her for being "so insensible despite our hard work." The sense of defeat and guilt over the years made the already introverted girl even more of a recluse. Gloomy, dull, and without any forte, she became someone overlooked by teachers and students in school. These dreary environments both at home and in school eventually led to her hearing things.
One day, after the end of the PE lesson, the health teacher of the school infirmary called out to Lin all of a sudden. This gentle, gorgeous teacher was especially popular among the students, so Lin was rather surprised.
"I noticed that you have some talent in martial arts. Will you be interested to learn from me?" asked the teacher with a smile.
This unexpected recognition, concern, and pat on the back that Lin had always longed for left her at a loss when they finally manifested, so much so that she fled like a coward. Right when she mulled it over while passing by the school's back alley, she chanced upon a scene that changed her life. Her gentle teacher was wielding a sword as a corpse lay by her feet, the corpse's bodily fluids slowly pooling on the ground...
Still, Lin did not tremble one bit, nor did she turn tail and run. The teacher who had long sensed Lin's presence handed the bloodied sword to the girl smilingly. Just like that, Toki took in the student she was most proud of.

When Lin first joined Night Chains, she immediately gave up her original, ordinary name and chose "Quill" as her code name. This was a choice initially made out of her admiration and envy of Toki, but as her abilities grew, she was no longer content to just be praised by her mentor, and neither did she wish to be forever inferior to Toki. Simply being a subservient feather was far from enough for her. After completing yet another critical mission, she changed her code name to "Lin" to start afresh with her own identity. Toki did not stop her protégé from doing so, nor did she remind Lin that the latter was becoming more and more like her unappeasable parents.
Outside of missions and filming, Lin is obsessed with all sorts of cute, intricate things, particularly Night Chains Land's mascot's plush toy series. Her collection can be said to be record-breaking, and it—alongside her exquisite appearance—is maintained with extraordinary effort. These adorable, sparkly things pile up to form a magical castle that lets her formerly frumpish, unconfident self hide and heal her wounds. Consequently, if anyone ever ruins her collection, they better prepare themselves to face a virtually hysterical, unhinged Lin.
In contrast to her love for plush toys, Lin will pretty much go to any lengths at all costs while on missions. She neither fears blood nor minds tainting herself from head to toe. However, the one thing she's afraid of is anything frail and alive, for that will jog back memories of the old her who would be helpless about everything in her surroundings. No matter how much effort it will take, Lin is willing to do it all so long as she never has to return to the time before she obtained her powers.
