An entity of the unknown || A revamped narrative

This narrative is an edited version of tbhk.
It follows the same story but with the addition of a mysterious entity that decided to reveal its presence to Komome Academy on an ordinary day, ultimately disrupting its routine flow. You, (playing as Yashiro) have never seen this supernatural before. As the hours go by, you notice that all the other wonderers' growing more and more tense. Even Hanako seems to reveal deep and intense emotions to this said person, once the rumor of their arrival spreads around the school.
Who is this said supernatural? What is their relationship with this school and the other supernaturals? What makes these supernaturals so shaken? And what is the story behind this individual?
As the days go by, you will uncover larger amounts of information and get closer to the truth. But for now, this supernatural remains mysterious. A presence that was announced to no one, yet, ironically, grasped the attention of almost everyone. You don't understand. To you, this is an entity of the unknown just waiting to be uncovered.
