The current year 2025
Anna Himiko a 24 years old girl with Supernatural ability, wanting to find out about an incedents that happened 15 years ago.She decided to join the Supernatural Detective's Agency.
"sigh....I think this is the place..." a blonde girl said before opening the door.
After opening the door,a tall mascular man greeted her."Good morning...umm...Are you the new recruit?" he asked,staring at her.
"Yes..I'm Anna Himiko"she answered.
(Anna Himiko is a blonde girl with waivy hair.She is 5'5 tall with blue eyes.)
"I'm Ishida Rinosuke,I'm the head of Investigation Department,"
"Welcome to the Supernatural Detective's Agency..nice to meet you,Anna Himiko" he added before pulling some files and papers from his drawer.
(Ishida): "First of all...whO the heLL recruited you?"
(Anna): "ummm,A woman named Kagisaki Itsuki told me to join in...since I have supernatural ability"
(Ishida): "Tsk...that damn..Itsuki " he mumbled.
Ishida: "Then is there a reason for you to join?"
(Anna): "I want to find out about something"
(Ishida):"Ahh,I see..."
(Ishida): "Here take this....this is your first job,but first you need a partner"
"It's too dangerous to do the job alone"
(Office staff):"But we don't have any available detectives boss.."
(Ishida): "There is one...you know him right.."
(Office staff):"Bossss, don't tell me..."
(Ishida): "Anna... go and pick him up,he will be your partner in this task" he said while showing her a map and a picture.
(Anna): "I understand...then excuse me.." she said before leaving and closing the door.
Jiro(office staff): "You should've warned her boss"
(Ishida): "(sigh)...Let's see how she will convince him..."
(Jiro): "I doubt that she can convince him to join...that guy never went to the agency for about 6 years,we lost contact with him for the past 3 years"
(Ishida): "Anna's real task is to convince Kasumi, nothing more..It's their choice if they'll continue the another task,I given to her"
Meanwhile Anna in her mission
"Whoaaa,this place is very dark" she said,amazed.
"Is this some kind of old school building or something...the hell..is he doing in this place?" she mumbled.
When Anna is approaching the stairs she feels uncomfortable like someone is staring at her.When she reached the second floor she saw lights in the rooms ahead.
"hello is anybody here?" she yelled and no one responded.
When suddenly someone grabbed her neck from the back.She then feel a pointed weapon poking the right side of her back."You're only allowed to speak,don't try to move and I'll kill you" the mysterious voice said.
"okay...I understand" she answered while trembling in fear.
(Mysterious man): "who are you?and why are you here?"
(Anna): "I'm Anna Himiko,I'm looking for a man named Kasumi"
(Mysterious man): "why are you looking for him?"
(Anna): "...to be my partner"
"Then I'm not interested in that Agency crap..leave me alone!" the man replied,letting her go.
Anna turned around,facing him.In front of her is a man probably younger than her with black hair and red eyes that later returned to normal.
"So you're Kasumi?..ohh wait.. how did you know that I'm from the agency?" she asked him out of curiosity.
"Because your department head is the only man I know,Who is foolish enough to send some unarmed girl here" he answered with a smirk,staring at her face.
"You should go home,it's getting dark" he added.
(Anna): "No not until I finished solving this case" showing him a picture.
(Kasumi): "I told you I'm not interested"
(Anna): "Then I'm going to solve it alone"
(Kasumi): "If you'll do that,you'll die"
(Anna): "How did you know?are you a god or something?"
"I have my own supernatural ability...I'm strong...I'm not a coward like you"
"tsk...it's your choice...don't blame me if you die" he said while walking away.
"If you have time to warn people about their death,why don't you just go and save them" she answered while leaving.
Kasumi's eyes widened from her answer."what's up with her...telling what to do" he mumbled while staring at her leaving the school grounds.
Meanwhile in the SDA office
(Ishida): "heeyy,Jiro...any updates from Anna?"
(Jiro): "No updates...boss"
(Ishida): "I hope she didn't think of solving that case alone... she's not dealing with humans after all"
(Jiro): "boooOSss..don't tell me you gave her that case... that's suicide for a newbie like her.."
(Ishida): "yeah it's dangerous...but only if she'll come alone"
(Jiro): "knowing that Kasumi, he will definitely let her go alone"
(Ishida) : "it's fine...I think she's not that reckless to come al..." he didn't even finish the sentence when the telephone ring.
(Ishida): "Hello this is the investigation department,what can I do for you?"
(Person on the line):"nothing much...I just wanna tell you...that the girl you send here will going to die"
(Ishida): "that voice..Kasumi?..wait what..did you let her go alone"
(Kasumi): "if you wanted to save her then hear me out"
(Ishida):"then let's hear it".....
After hearing the rescue plan Ishida ordered Jiro to go and help Kasumi.
Meanwhile Anna on her Mission
Anna opened the envelope that contains informations about the crime scene and then she reads it. She needs to investigate a crime scene in Shifukuda street near the construction site.
Where two corpses of workers were found this morning.The corpses organs and limbs are all missing and all of them have bite marks on every part of their body.
"That's horrible...what kind of creature would do that..." she whimpered to herself.
When she's approaching the construction site she heard groans as if someone was getting tortured to death.She then started running to find where's the noise coming from.She saw some blood stains near the walls she then assumed that it was from the corpses this morning.
"H..el...p...me!....AhhhHHH" screamed from the warehouse near the construction site.
She picked up her phone and open the flashlight.When she entered the warehouse she saw a woman around her late 20s and topless.Her arms are deeply wounded probably because someone tried to restrain her.
"Heyyy...are you okay?Who did this?did you see his face?" she asked and started panicking.
The woman simply pointed her fingers upward.Anna then slowly looked above her head.
"Wha-...what the hell is that thing?" Anna screamed while trembling.
