"The purpose of exorcism on humans is to drive out the ghost possessing a person and seal it somewhere else so it can't possess another person.

  When you performed exorcisms at home, you probably thought you just needed to drive out ghosts, but the most important part of exorcism rituals is sealing the expelled ghost.

  If you just drive out a ghost, it will immediately find another host or wander around until it possesses its another host again.

  That way, instead of eliminating the evil spirit, you're just passing it on to someone else.

  So remember, when performing an exorcism, you absolutely need an object or living thing to act as a vessel."

  Professor Myers brought a bottle of black water and sprayed it on the apple.

  "This water I'm spraying is just rotten dusty water. It's not cursed black water.

  You'll learn how to make rotten water later in Professor Francesca's Spiritualism class, so for now we'll continue with the lesson as is."

  Professor Myers brought a glass pitcher and sprayed the liquid inside in a circle around the two chairs.

  "This is holy salt water, creating a minimum barrier so the ghost and curse attached to the doll can't go beyond the salt water boundary.

  When we recite scripture in this state, it's to guide the ghost so it can't escape the circle and will attach to the delicious apple sprayed with rotten water."

  After finishing speaking, Professor Myers stood behind the doll holding a Y-shaped cross in one hand and holy water in the other.

  The students blankly watched Professor Myers.

  "Now I'll perform an actual exorcism ritual.

  As I said during theory time, the most important part when performing an exorcism ritual is reciting the appropriate scripture passage for the situation.

  However, in most cases, especially for new students like you, there are set usable exorcism passages and memorizing them is basic.

  Right now, I'll perform the exorcism ritual while reciting Scripture Song #1 'Fear to the Betrayer' that you've already memorized, so watch carefully and follow along."

  "..."

  "You evil spirits shall remember your sin of betrayal upon seeing my form.

  I sing and dance before you, so slaves of death shall hide their form and flee to dark and empty places."

  Professor Myers repeated this passage. Then the doll visibly started trembling in real time.

  When the professor raised his voice more to heighten the atmosphere then sprayed holy water on the doll, the doll stopped trembling and 'poof!' something like white steam burst out.

  While all the students watched that steam-like thing intently in surprise,

  "Woof woof woof woof!"

  The white steam transformed into what looked like a puppy then smoothly entered the apple.

  "What was that? Isn't that a puppy?"

  "Haha, that's Winnie."

  "What? Winnie?"

  "You mean Winnie, our school's ghost dog?"

  "That's right, since I obviously can't use real evil spirits in new student classes, I got help from Winnie, our school mascot."

  Professor Myers answered.

  "Aw..."

  Rumi was secretly disappointed. She thought it was below standard to practice with just the school mascot ghost dog, even for first-years.

  Hadn't even the spirit summoning ritual she performed at home been much more sophisticated?

  "So when the exorcism process ends like this, we need to handle the aftermath of this apple.

  Usually there are various methods like storing it submerged in holy water or holy oil, coating it with holy oil and burning it far away, or burying it, but we won't go that far today.

  But one thing to remember is that it's impossible to permanently remove or make a soul disappear.

  It can be transfered, transformed, corrupted, combined and split, but its essence is absolutely preserved no matter what.

  And remember, what you're learning now is just the basics of basics. If you had rashly performed this kind of exorcism at the library today, dozens of people would have been cursed altogether.

  Stolen novel; please report.

  So when these things happen to you, especially new students, just follow the rules for now.

  That means if you can't find a teacher immediately, even if you have to abandon your friend, just pour holy water on yourself and run away."

  "Professor, does that mean what we're learning today is useless?"

  "No, obviously it's meaningful as a foundation for learning more advanced things.

  And if there's no teacher and you can't run away, trying an exorcism before dying might be better."

  The children fell silent again.

  "Winnie, come back."

  When Professor Myers called out, Winnie popped out of the rotten apple and jumped cheerfully back into the stuffed doll.

  "Now we'll start practicing.

  Line up and each person will perform the exorcism ritual one by one. Everyone line up in front of the chairs."

  When practice started, the students suddenly began competing for spots in line.

  Now that they knew the ghost was Winnie, everyone seemed to want to try the exorcism ritual first.

  Unexpectedly, Eve became the first person to perform the exorcism ritual.

  Eve maintained a very devout posture and clearly recited the scripture passage while holding scripture in one hand and a Y-shaped cross in the other.

  Soon the doll started trembling and Winnie popped out and went into the apple.

  "Well done, Eve. Kids, just do it like this. Don't try anything strange."

  "Yes!"

  The students shouted.

  But after Eve, no one seemed able to perform as perfect an exorcism ritual.

  Some stumbled over words, some didn't spray holy water.

  And some... especially Niel, performed the exorcism ritual so awkwardly that Winnie showed no signs of moving at all.

  "Strange... Niel, your exorcism ritual doesn't seem to have major problems, but I don't understand why Winnie isn't responding at all..."

  Though Professor Myers said he didn't understand, Rumi thought she did.

  It was probably because Niel's split personality curse was too severe.

  Professor Myers continued the class while pointing out students' mistakes.

  Winnie kept going back and forth between the doll and apple, resetting each time an exorcism ritual was performed.

  After Raoul also perfectly performed the exorcism ritual like Eve, it was Rumi's turn.

  But Rumi was thinking something slightly different.

  She had scoffed at seeing such a basic exorcism ritual being performed.

  This level of exorcism was as easy as pie.

  So Rumi had a responsibility to show her more sophisticated exorcism ritual.

  Rumi confidently stood before the chairs holding a Y-shaped cross and holy water.

  Instead of today's learned scripture song, Rumi began reciting the scripture song Bertin had taught her.

  "Kill, kill, for here are the weak ones. They are my enemies. Gouge out their eyes, tear off their limbs,

  kill both mother and child until their bloodline ends.

  Let hatred drive them mad until they lose themselves slaughtering their enemies..."

  Though Rumi felt nauseous reciting this passage, she could bear it this time.

  But as soon as she recited the scripture song once, a cold wave seemed to freeze everyone in the classroom.

  "You... what did you just recite?"

  Professor Myers stared at Rumi with shaking pupils.

  At that moment, a whitish form was seen slipping into the apple.

  Everyone's eyes focused on the apple.

  Nothing seemed to be happening to the apple... no, two strange holes started appearing vertically on the apple.

  While Rumi, the students, and even Professor Myers stared intently at what was happening to the apple, an eyeball popped out of one hole on the apple.

  And it started speaking through another hole on the bottom.

  "Oh praise uh the Death God Monalith praise uh."

  The apple started singing strange songs in a nauseating voice.

  Rumi sensed something had gone seriously wrong.

  But the apple's strange transformation didn't stop there.

  Hands and feet sprouted from the apple, like stems, and started writhing like a cursed insect.

  "Aaaaah!!!"

  The students were terrified by that disgusting sight and backed away to the rear of the classroom.

  "Ugheck, oh God of Death why have you become the God of Life?"

  As the apple was babbling and thrashing, about to fall from the chair, Professor Myers hurriedly poured holy oil on it and set it on fire.

  "Keeeyaaaack ugheck ugheck ugheeeeck!"

  The apple screamed in pain. As smoke-like souls tried to escape from the apple, Professor Myers covered it with a glass lid.

  The inside of the glass lid quickly filled with smoke.

  "All of you get out of here right now!"

  Professor Myers shouted.

  "Aaaaah!"

  The children ran out of the classroom with shocked eyes.

  Rumi also ran out of the classroom in confusion and stood at the door.

  The shocked students looked at Rumi with wary eyes.

  Even Raoul had a very serious expression.

  "What did you do?"

  Just then Eve glared at Rumi and asked.

  "Um... I just..."

  Rumi had nothing to say. She felt like anything she said would only make the situation worse.

  "Where did you see that passage?"

  Dave also spoke up from the crowd.

  "Um..."

  Rumi just made a confused expression without speaking.

  "Everyone, since Rumi seems shocked too right now, let's give her some time."

  At that timing, Raoul took Rumi aside away from the children.

  "Are you okay?"

  "Um... I don't know...? I might be cursed..."

  "What?"

  "No, I'm joking. Actually I'm fine. I've done this several times before but then... Umm..."

  Rumi suddenly remembered that unpleasant things happened every time she performed this exorcism ritual.

  "Do you perhaps know where that passage is from..."

  "Wait, I just remembered something..."

  Rumi cut off Raoul's words and ran to Niel.

  After taking Niel to a corner, she whispered:

  "Niel, you and I learned this passage from Bertin, do you know what's wrong with it?"

  "Umm... I don't know..."

  'Thud... bang... rattle'

  Just then strange sounds came from the classroom, then the door opened and Professor Myers showed himself.

  Professor Myers spoke with very tired eyes.

  "Kids, class is over for today. So everyone go to the cathedral until next class."

  "Professor, Aren't you going to explain what just happened?"

  "No. Before you go, everyone forget the song you heard from Rumi today. Since it seems Rumi didn't exactly know what it was either, don't ask her unnecessary questions.

  Sigh, Now Rumi you stay behind, let's talk for a moment."

  "Yes..."

  Rumi thought what was coming had come and gave Raoul and Niel a look to go ahead.

  Just then she witnessed the slightly ominous sight of Eve clinging to Niel to ask questions.

  Rumi followed Professor Myers back into the classroom.

  Professor Myers quietly walked to the chairs where the incident occurred and Rumi followed the teacher inside.

  The burned apple was already gone.

  "Where exactly did you learn that song?"

  Professor Myers turned around and sharply questioned.

  "Um... I picked it up somewhere."

  Rumi had no intention of telling who taught her.

  "Hmm... I heard both you and Niel came from the outside. You probably learned it from someone while coming here, but you need to forget everything you learned there."

  "What? Why? What was wrong with it?"

  "Sigh... what you sang wasn't a passage from scripture."

  "What?"

  "It's a passage from books that summon evil spirits. Black magic used by witch cults!"
