"Hmm, you're quite capable, aren't you?" Remilia praised Kars after being found, acknowledging his ability to see through her and Sakuya's attempt to hide. Kars simply smiled without saying anything.
"But you haven't found Flandre yet?"
"Not yet. Little Auntie Flandre's hiding spot is quite difficult to find." Kars shook his head, explaining that the most likely place Flandre was hiding was in the Great Library. Remilia nodded in understanding; it was indeed a very difficult place to search.
"Then let's find her together!" Remilia, who was clearly not ready to quit the game, grabbed Kars and ran toward the Great Library. Sakuya quietly followed. Once inside the library, the three split up to search. Flandre, who was hiding, noticed this. She hadn't expected this turn of events. However, Remilia joining the game only made it more fun and exciting for her. At the same time, her copies, which were hiding elsewhere, also converged on the Great Library, clearly intending to make the game more interesting.
"Little Auntie, have you found anything?"
"I feel like someone is nearby, but I can't find them. What about you, Sakuya?"
"The same here." Sakuya also felt like she was being watched. With both of them experiencing the same feeling despite being far apart, Kars suspected that a copy of Little Auntie Flandre was nearby, otherwise, this wouldn't happen.
Then, Flandre's laughter echoed from nearby, prompting Kars to move immediately toward the sound. Sensing a clear movement behind a bookshelf, he quickly rounded the corner, ready to catch the person. At the same moment, Remilia also emerged from the adjacent bookshelf, and their heads collided.
"Ouch!" Kars and Remilia both clutched their heads and crouched down, crying out in pain. Sakuya, who followed them, watched the scene, feeling her nose start to bleed again.
"Little Auntie, why did you suddenly come out from there?"
"I should be asking you! Why did you come out from over there? I had just spotted Flandre, and now I've lost her!"
"Me too!" Flandre's laughter then emerged from nearby again, making Kars and Remilia exchange a look. They realized Flandre must have been playing a trick, deliberately luring their actions and using the bookshelves to block their view, making them mistakenly think the person on the other side was her.
"Ugh! Flandre tricked us!" Realizing this, Remilia felt that if she didn't catch Flandre now, she would truly lose face. "Flandre, I'm getting serious now." Declaring this, Remilia began her search again. Kars looked around. Although the laughter he heard didn't give him a clear direction, he was certain that Little Auntie Flandre had placed a copy, or herself, in this area. Someone had to be nearby.
Soon, Kars noticed movement nearby, as if trying to lure him closer again. It seemed she wanted to repeat the previous scenario, but Kars wasn't falling for it again. After pinpointing the direction, he threw a solar-attribute light orb, which instantly released a blinding flash.
"Ah!" Hearing Flandre's cry, Kars immediately rushed in that direction. He saw Flandre covering her eyes with both hands to block the intense light. He instantly wrapped his arms around her.
"Got you! Little Auntie!"
"Kars, you cheated!" As the intense light faded, Flandre dropped her hands, feeling frustrated that Kars had used such a trick to catch her. Otherwise, she wouldn't have been caught.
"Well, you wanted to play tricks, Little Auntie. If you had just hidden properly, I wouldn't have found you." Kars felt no issue whatsoever with using a small trick to catch his opponent.
"Hmph!" Flandre huffed in annoyance, then asked Kars, "So, what were you and Koakuma doing kissing here earlier?"
"Eh? You… you saw that?!" Kars's slightly smug expression instantly changed when he heard Flandre's question. Koakuma had said it was a secret between them that no one else could know, but Little Auntie Flandre had seen it.
"Mhm. I watched Kars tackle Koakuma, and then she kissed your mouth. So, Kars, what were you and Koakuma doing that for?" Faced with Flandre's curiosity, Kars scratched his head in frustration.
"That… that's a secret between me and Koakuma that I can't tell you."
"A secret? What kind of secret? Flandre really wants to know!" Hearing this, Flandre became even more curious and wanted to understand clearly.
"I can't. I promised Koakuma not to tell, so I can't tell you, Little Auntie."
"But I already know it! So it's not just a secret between the two of you, is it? It's not a secret anymore since I know it." If the secret was already known to someone else, then it wasn't a secret anymore, so why couldn't he talk about it?
"That sounds true…" Since Flandre knew, keeping it a secret was basically impossible.
"Then you can't tell anyone else, Little Auntie. That way, it will be a secret between the three of us."
"Mhm! Flandre absolutely won't tell! Not even Sister." Kars relaxed, and then told Flandre everything Koakuma had told him, as well as what they had done together. Flandre listened, understanding some parts and not others, but one thing was clear: loving someone meant doing things like that, and being able to accept it showed genuine affection.
"So, that's how it is, Little Auntie, do you understand now? You really can't tell anyone else about this."
"Mhm, Flandre understands." Flandre nodded and stepped closer to Kars.
"Little Auntie, what are you doing?" Kars asked, confused by Flandre's closeness.
"Flandre wants to see if she really loves Kars." Without hesitation, she kissed him, then emulated what Koakuma had done to Kars earlier. Flandre felt nothing unpleasant about the experience. This confirmed for her that she truly loved Kars.
"Oh, what the… ?!" Sakuya, who had come over due to the commotion, witnessed Kars and Flandre kissing. Her nosebleed finally erupted uncontrollably.
