Seeing Rias' new Pawn that had the power of the Welsh Dragon, Ddraig, Sona starts looking for a new source of power to match her friend.
"A Pawn with the power of a Sacred Gear, you got the jackpot this time Rias" - Sona, the president of the Kuoh Student Council said to herself as she watched through the windows of her building the newly transferred students arriving at the school. Her job would now become harder.
As she watched them enter the school, her heightened demonic senses isolated one of them in particular. He looked like a regular person, a boy with light, curly, short pink hair and red eyes, a bit skinny and seemed to be slightly taller than Sona. In his backpack, she caught a glimpse of what seemed to be a white flute.
"Tsubaki" -
"Yes?" -
"That boy, the one with the pink hair, as soon as you can bring him to me" -
"Is there something wrong with him?" -
"Nothing wrong, but something is definitely special about him. I need to talk to him" -
"Understood" -
Investigating the name of the newly arrived student, Tsubaki quickly caught on who he was thanks to the school's profile of him: Yukio Furigana, a student originally from Kyoto whose family had to move due to problems not specified in the report. Thanks to it, Tsubaki also learned where he was studying, he was a second grader at class 2-B.
Arriving at his classroom, she entered and asked for him, earning Yukio a look from all of his classmates who were jokingly saying "He must have angered Sona by walking weird".
"So... I'm not against seeing the Student Council President, but did I do something wrong?" - Yukio asked.
"Sona wants to see you, she'll explain when we get there" -
The walk felt eternal for Yukio. The halls of the schools were silent and everything that could be heard were their footsteps until they arrived at the Student Council's room.
"I brought him Sona" -
"Thanks Tsubaki. Please, join me" -
With Sona's Queen standing by her side, she signaled the boy to sit on a chair in front of his desk, which he did after a second of hesitation.
"So, you're Yukio Furigana, right?" -
"Yes..." -
"Please, don't be nervous, we're not here to hurt you, we simply want to talk about something" -
"What exactly...?" -
"When I looked at you arriving at the school, I felt something weird. You're... Not a normal person, aren't you?" -
"What?" -
Sona looked closely at him, noticing how he grabbed his flute and held it in his right hand.
"Your flute, can I borrow it?" - Sona asked as she extended her hand and opened it.
"Sorry, but it's an important family relic, I can't allow someone else to hold it" -
"Really? Interesting" - Sona got up from her seat and walked towards Yukio - "Then I'm going to assume that my guess of you not being a normal person is correct since this flute is emanating energy" -
Yukio froze on the spot. He didn't know what to do or say to get himself out of that situation. His shock was only increased when Sona took some distance and he observed how black wings like those of a bat appeared in her backs.
"Tell me Yukio, do you believe in demons?" -
