*reader's discretion, disturbing scenes
A week had passed since that incident, Sky is not yet back from the Mythical Dimension but no one seems to feel anything wrong about that since he did that almost all the time. However, Itsuki had been acting weird since he visited that cathedral with Ai. He went to that cathedral every day after school, even when there were club activities in school. Ai and Seito worry about him, they decide to follow Itsuki to the cathedral to investigate what is happening to Itsuki, however, Seito is busy with the aftermath of the slime disease outbreak that had happened about a month ago, so he is unable to join them, thus only Ai the one that followed Itsuki to the cathedral, or rather she was dragged along by Itsuki because of the advice from the nun they met that day
However, there's something different about that cathedral today, whenever Itsuki went to the cathedral, that young nun will greet Itsuki in the shortest time. But this time, the nun is no where to be seen in the cathedral.
"Sister Anna is not here, this is unusual." said Itsuki.
"Could it be that she is in another room?" said Ai.
Then Itsuki walks to the side room without waiting for Ai. He knocked on the door but no one answer, so he tried to open the door, the door is not locked, so he walks in. Sister Anna is not in the room but there is something weird about the room, there's a secret door at the corner, half opened. Although it's not polite to randomly enter someone's room, but out of curiosity and worry about the nun, Itsuki decides to peeps in the secret door. But before he even gets near the secret door, a pungent scent of blood and rotten flesh had drawn his attention.
"Did something bad happens to Sister Anna?" he thought before running towards the. The moment he peeps in, he realized that something is really wrong with that nun...
"Ah... You don't eat your meal again, is it not delicious, or do you want me to feed you."
Sister Anna is talking to a 'child' that seated silently on an iron chair. We'll, instead of a 'child', it's a humanoid creature that is formed by connecting different body parts of children from different races and nations, it looks like a 'doll' that is patched with cloths of different colors with very bad stitches. To make the situation even more disturbing, that 'creature' is actually alive but unable move and can only some 'eerrrr' noise without any emotions, its eyes look blank making people wonder if it is actually just a corpse that breathes and make weird noises.
Around the nun and the 'child', are mutilated bodies of little children from different races and countries, some have their head chopped off, some have their eyes dug out and some have their torsos completely removed. These terrifying scene somewhat had 'awakened' Itsuki from some sort of charm, he is slightly confused about what he is doing in Sister Anna's room, then he recalled what Ai told him about her dream that night and realized that what he sees right now are actually matches with Ai's dream. Slightly shocked and frightened, he slowly stepped back and trying to sneak out from the cathedral with Ai, before the nun notices them. However...
"Why are you leaving? Don't you want to find out what I'm trying to do?" said the nun while slowly turning her head showing her slightly sinister looking face with a wide disturbing smile.
---------------------------------------------------------------------------
Thousands of years ago, there's a powerful goddess who was the ruler of a magical forest, she was beautiful, kind and pure, however, the stupidity of some human beings had sparked the darkness inside her, and this darkness grows slowly until one day she finally 'swallowed' by her own darkness. She tried to destroy all the humanity in order to 'preserve' her forest, in order to stop her, the Ancient Vampire Master Vlad X Dracula had a great fight with her but he was unable to finish her off as he knows that her nature wasn't bad originally, so, he sealed her soul into a piece of gemstone.
"When the day people with different colors, races, and nations can finally unite together, it will be the day for your freedom." is what Dracula said before she was totally sealed into the stone.

Present.
"Hey, have a look at this, aren't this 'child' here a product of unity between different races?" said Sister Anna while embracing the 'child' with a rather disturbing look.
"But I still lack of one material to 'connect' them all... Or perhaps, are you that final material?" said the nun.
Then without any warning, her hands turn into two big drills, it extended and pierced towards Itsuki. Unprepared for the sudden attack, Itsuki went blank out and doesn't know how to react. However, he did not get hurt by the attack, Ai guarded him from in front with her small and delicate body, her shoulder is getting pierced through by the drill. The nun mercilessly lifted her up with the extended hand.
"Ai!" Itsuki shouted in shock. Before they could react, the ground cracked and vines emerged from the cracks and tangled together forming some humanoid creatures. The eyes of the creatures glow in red light and start moving towards Itsuki and Ai...
