Kaguya-sama Wants My Surrender!

In the living room.

A succubus girl stood quietly behind Amamiya. With delicate wings, a heart-shaped tail, long burgundy hair, pointed ears, and a pair of small fangs peeking out at the corners of her mouth, she looked every bit the part.

"Oh~ what a cute boy."

The succubus wrapped her arms around Amamiya's neck from behind, resting her chin on his shoulder. She turned her face slightly, blew a soft breath into his ear, and gently poked his cheek with one slender finger.

"Hey, Amamiya-kun, won't you let me eat you?"

"I haven't showered yet." Amamiya replied calmly, still focused on his phone. "Maybe I should go shower first?"

Umi, still in character, gently bumped his shoulder with her chin and murmured, "I'm a succubus now, here to eat you. So just play along, alright?"

"Yes, yes," Amamiya replied, sighing with feigned reluctance.

But really, who could resist? If a succubus who's both stunning and cute wanted to "eat" you, most people wouldn't even need seducing—they'd throw themselves down without a second thought.

Does it even matter if it's a succubus? Hardly.

Once someone's mind is clouded by desire, even the strangest fantasies seem perfectly reasonable.

"Role-playing proficiency just went up by 1%—it's now at 43%," Umi announced after checking her character stats. "Hold still, Amamiya-kun. Let's keep up the act."

Amamiya raised an eyebrow. "Why not go role-play with Inui-san?"

Umi put on an innocent expression. "Oh, JuJu-sama's still so young. I'd feel too guilty."

Amamiya continued scrolling on his phone. "But you don't feel guilty trying to eat me?"

"Not at all," Umi said with a small grin. "In fact, I'm pretty thrilled about it."

"…"

The roleplay continued.

"It's my first time in the human world, and meeting such a cute boy… Ah, these two wonderful things at once—tonight is going to be like a dream."

Umi traced circles on Amamiya's chest with one finger, and then, as a final flourish, gently nibbled on his ear.

"I want everything that Amamiya-kun has," she whispered, her voice low. "Stay with me until dawn, won't you?"

But that's simply impossible.

Limits of human endurance make such a feat absurd unless you have superhuman abilities. Nobody could survive such intensity for an entire night!

Amamiya's brow twitched at her surprise attack. Despite himself, he couldn't help but protest, "Why are you…so good at this?"

Umi giggled, making a peace sign as she boasted, "This is all knowledge from games and manga!"

Maybe learn something useful instead, he thought. You ranked even worse than Chika in the last exams; at this rate, you'll be at the bottom soon!

"You know," Umi murmured thoughtfully, resting her chin on his shoulder, "this character I'm playing really reminds me of a character from that manga 'As a High School Light Novel Writer, I'm Harassed by Nightmares Every Night'."

Amamiya squinted at her. "You realize that's just a family-friendly, four-panel gag manga, right? Completely different from whatever you're doing here."

Other people get nightmares… but the succubus you're playing just seems ready to drain her victim dry!

"It's like a twist on an online trope," Umi murmured, tracing circles on Amamiya's chest with a lazy finger. "The succubus returns to repay a childhood kindness, and then..." She trailed off with a mischievous smile. "But I'll stop there. The role-play percentage is starting to drop."

The succubus glanced toward Amamiya's neck and Adam's apple, eyes glinting as she suddenly leaned in and bit him. 

It didn't hurt—more like a kitten playfully nibbling. Just a gentle nip, enough to jolt him.

"Click!"

Amamiya's eyes widened in surprise. 'You actually bit me? You're getting way too into this!'

"Whoa, the role-playing level just went up so fast…" Umi's eyes sparkled with intrigue as she watched the stat increase, her gaze shifting back to Amamiya's neck before she leaned in and bit him again.

Amamiya's eyebrow twitched, and he sighed. "You're still biting?"

Through a muffled voice, Umi replied, "A succubus biting someone's neck is totally normal."

'That's more of a vampire thing,' Amamiya thought, 'shouldn't a succubus be biting somewhere else?'

"It stings a little," Amamiya warned, raising an eyebrow.

"Oh, sorry!" Umi quickly released her hold, looking slightly embarrassed. "Didn't mean to go that hard."

But then, noticing the faint teeth marks she'd left on his neck, she froze. Her mind suddenly short-circuited, and, without thinking, she leaned in and brushed her tongue gently over the marks.

The damp warmth on his neck made Amamiya tense up. He turned to look at her, caught completely off guard.

'You're a natural at this, aren't you? Have you been a succubus in a past life?'

"Ahem!" Umi's face flushed a deep red as she hastily stood up, covering her mouth. With a blush as bright as a summer sunset, she stammered, "I—uh—need the bathroom!" and darted out of the room.

"…"

A few moments later.

The door creaked open, and out stepped another figure—a magical girl dressed in a dark outfit.

Amamiya turned to see her and had to admit she looked adorable in costume.

Compared to Umi, Sajuna was much more self-conscious. She glanced at Amamiya nervously, crossing her arms over her chest.

'No need to cover up,' he thought, fighting a twitch of amusement. 'It's not like you're hiding much.'

"JuJu-sama, you're adorable!" Umi exclaimed as she reappeared from the bathroom, spotting the transformed magical girl. She placed her hand on her hip confidently. "Well, Amamiya-kun, what do you think?"

Amamiya raised his right hand above his head in a mock oath, speaking with an air of solemnity:

"Winter is coming. From this day forward, I shall protect JuJu-sama till my dying breath."

"That's so over-the-top!" Umi protested, puffing out her cheeks.

Sajuna shot Amamiya a sidelong glance, muttering, "…You're just quoting the Night's Watch."

Amamiya took a slow sip of his drink. "So, did the role-play work?"

Sajuna, slightly disheartened, nodded. "It worked, but my character compatibility is still below 20%."

Despite the effort she'd put into her costume, her connection with the character felt disappointingly low.

"Don't worry, you can raise compatibility with more role-playing practice," Umi reassured her with a smile. "My succubus level is over 50% now."

'Given everything you've done, it would be strange if it hadn't gone up!'

Amamiya raised an eyebrow at the number. "Does anything special happen when the role percentage hits 50%?"

When he played a hero the day before, he'd received a game notification that hinted at unlocking unique abilities upon reaching 50% in a role.

Perhaps something like… the legendary Shield Hero?
