Some people were really interested in the 'Onii-chan' angle for Blake instead of the mentor one. Well, ask and you shall receive. I put it in along with a small second segment. Enjoy the cringe overload.

Oh, and Merry Christmas.

Adam clenched his jaw, shaking his head as he walked toward a nearby bench. Blake had been the reason he joined the MenToo movement in the first place, though he rarely talked about it. When he first met her, she'd been just another ambitious Huntress, eager to prove herself, with stars in her eyes and a determination to change the world. He'd seen her as the little sister he never had, someone he could mentor, guide, and protect in his own way - even without Aura.

He'd even offered to train her in close combat, sharing techniques he'd developed over years of trial and error. At first, it seemed like a normal mentor-student relationship. Blake was eager to learn, and her dedication was almost admirable. But then the...incidents started.

At first, Adam brushed it off as harmless quirks. Blake was young. Huntresses were...eccentric, to put it kindly. So when she started calling him Onii-chan during training sessions, he assumed she was just being playful. Acting like a Mistralian weeaboo like some of the other people in their neighborhood.

He was wrong.

The first time it happened, they had just finished sparring. Blake had landed on her back, panting, hair splayed out around her. Adam extended a hand to help her up, and instead of thanking him like a normal person, she smiled sweetly and murmured, "Thank you, Onii-chan. I don't know what I'd do without you."

Adam froze, blinking down at her, "...What did you just call me?"

Blake sat up, tilting her head innocently, "Onii-chan," she repeated, her voice a soft whisper that grated his ears, "Isn't that what big brothers are called in Mistral?"

Adam's eye twitched, "We're not in Mistral and I'm not your brother." He saw her like a younger sister, but he wasn't calling her that.

"But you feel like one," she insisted, hugging his arm suddenly, "You've been teaching me so much. It's like you're helping thaw the ice around my heart..." She gazed up at him with wide, shimmering eyes that practically screamed tragic anime heroine.

Adam, on the other hand, felt like screaming for entirely different reasons, "Blake, I'm not thawing anything. We're just training. Let go of my arm."

Instead of letting go, Blake nuzzled into his shoulder, sighing dramatically, "I knew you'd be embarrassed," she whispered, loud enough for him to hear, "Onii-chan is so shy about his feelings..."

Adam pried her off like she was some kind of barnacle, "We're done for today. Go home."

She didn't.

In fact, the next time they met up for training, it got worse. Blake arrived late, gliding into the room with a book under her arm. Adam didn't even have to guess the title - Thawing the Ice Queen's Heart. One of her favorites. She sat down cross-legged in front of him, holding the book up for him to see with a sly smile, "Onii-chan," she purred. Literally purred. Such a horrible stereotype "Don't you think the dynamic between the strong, stoic older brother and his adopted sister is...beautiful?"

Adam stared at her, unblinking, "Why are you holding a book about forbidden sibling romance before a sparring session?"

Blake brushed her hair behind her ear delicately, "It just...inspires me. Sometimes I can't help but imagine us in their place."

Adam sighed and pinched the bridge of his nose, "We are not in their place."

"You're right." Blake nodded sagely, "I could never match the heroine's tragic backstory. Her suffering pales in comparison to mine." She let out a theatrical sigh, lowering her gaze to the floor, "No one understands the loneliness of being a Huntress, wandering this cold, unfeeling world...except for you, Onii-chan."

Adam groaned and slapped a hand to his forehead, "Blake, you have parents. Loving parents that anyone would kill for. You live with them."

"That's true," Blake admitted, clasping her hands over her chest dramatically, "But they don't understand me the way you do. You see the real me."

"The real you needs therapy," Adam muttered, but Blake wasn't listening.

One time, during a meditation exercise, Blake actually scooted closer to him and leaned against his shoulder with a soft sigh, "It's so comforting being near you," she whispered, her breath hot against his neck, "Your presence makes me feel safe...like I'm finally home."

Adam opened one eye, scowling down at her, "We're sitting on floor mats, Blake. In a gym."

"Onii-chan's sense of humor never fails to brighten my day," she giggled softly, tilting her head toward him.

Adam stared at the ceiling for a long moment, silently questioning every life choice that led him here. It wasn't just the little sister act that grated on him - it was the sheer commitment. Blake didn't break character, even in public. Once, while they were walking through Atlas during a trip, she loudly complained, "Onii-chan! You're walking too fast. Wait for me!" As if she couldn't easily outpace him with her Aura-empowered strides.

Heads had turned. He still hadn't recovered.

And then there was the absolute final straw.

Adam had been sitting under a tree during their break, eyes closed, enjoying the rare peace. Blake approached quietly, and just when he thought maybe - just maybe - she was going to act normal for once, she knelt beside him and whispered:

"I made you lunch, Onii-chan~."

Adam opened his eyes to find a neatly packed bento box sitting in her lap. She'd decorated it with hearts.

"No," he said immediately, standing up.

"But - "

"No."

Blake pouted, cat ears drooping slightly, "Onii-chan, don't you trust my cooking?"

Adam looked her dead in the eye, "Not when it's wrapped in romantic subtext, I don't."

Blake sighed wistfully, "I'll win you over eventually," she said with unnerving confidence, "One day, you'll stop fighting it."Adam didn't wait around for the rest of the conversation. He left the park without looking back, muttering to himself the entire way.

Adam had thought - hoped - that the "Onii-chan" phase was the worst of it. He was wrong. Because shortly after Blake realized the big brother act wasn't getting her anywhere, she pivoted hard into something even more unbearable.

Tsundere.

It started subtly - at least, as subtle as Blake could manage, which wasn't saying much. They were sparring, and Adam had just disarmed her with a clean strike to her wrist. It was easy. TOO easy. He expected the usual grumbling or maybe another weird, flirty comment. Instead, Blake crossed her arms, turned her head with an exaggerated hmph, and muttered, "It's not like I wanted to win or anything. Stupid Adam."

Adam blinked, "What?"

"I let you win," she continued, eyes narrowed at the wall like it had personally offended her, "You're lucky I went easy on you. Idiot."

Adam's sword lowered slowly, "...I disarmed you in three seconds."

"Three seconds that I allowed to happen!" Blake snapped, cheeks flushing red as she adjusted her gauntlets.

Adam stared at her, expression unreadable, "...Are you serious right now?"

"I-It's not like I care if you believe me or not!" Blake huffed, tugging her hair tie free to let her long black hair fall dramatically over her shoulder, "I don't even know why I bother sparring with you. It's not fun or anything!"

Adam pinched the bridge of his nose, inhaling deeply, "Okay. This is new. What's this supposed to be?"

"I have no idea what you mean." She flicked her hair, throwing in an exaggerated eye-roll, "It's not like I care about your opinion. D-Don't misunderstand or anything."

Adam squinted at her, "...Did you hit your head?"

"No! Ugh, you're the one being dense!" Blake crossed her arms tighter, practically vibrating with frustration, "Why do you always have to be so - so cool all the time! It's annoying!"

"Cool?" Adam repeated flatly.

"Whatever! It doesn't matter!" Blake's face reddened further as she fumbled to grab her sword again, "S-Stupid Adam..."

Adam slowly lowered his weapon, holding up a hand, "Alright, stop."

"What now?" Blake snapped, glaring at him from the corner of her eye.

Adam exhaled, eyes narrowing, "I need to ask you a very important question, Blake. Are you...trying to act tsundere right now?"

Blake flinched visibly. Her cat ears twitched, "W-What? No! Why would I- "

He pointed at her accusingly, "You are."

"I'm not!"

Adam crossed his arms, staring her down, "You're literally doing all the tropes. The crossed arms. The 'idiot' comments. The hair flicks. I've seen anime, Blake. I know exactly what this is." He'd been a teenager once in his life. He too had his weeb phase, blindfolding himself and claiming that he'd studied the blade. At least he actually did study the blade...

Blake's face went beed, "I-I just...maybe I'm frustrated! That's all! I can be grumpy sometimes, okay?"

Adam leaned forward slightly, his eyes narrowing, "Hmph."

She snarled in embarrassment, "D-Don't mimic me!"

"Oh no," Adam said, his tone deadly serious, "I just misunderstood. I didn't know you were going to let me win, Blake. You're clearly on a higher level than me. I'm just a dumb idiot who doesn't understand your feelings."

Blake's face burned bright red, "Y-You're mocking me - "

"I'm thawing your cold heart, Blake," Adam deadpanned, "That's what this is, right? That's what you're angling for?" Her lip trembled as she took a step back, suddenly looking like she wanted to flee the room entirely, "Admit it," Adam pressed, refusing to let it drop. He was far too annoyed to, "You're doing this on purpose."

"I thought it might...work," she muttered weakly, barely audible, "Guys like tsunderes."

Adam groaned and dragged both hands down his face, "Oh my gods, Blake. Guys like fictional tsunderes. Real-life ones are just- "

"Cute," Blake cut in, still glaring at the floor.

"No," Adam corrected sharply, shaking his head, "It's frustrating. You can't just insult me and expect me to-"

"I-It's not like I want you to like me or anything, baka!" Blake blurted out, her fists clenched at her sides.

Adam froze mid-sentence. His mouth opened, but no sound came out.

She had actually saida baka. In real life. In Remnant.

Adam lowered his hands and stared at her, wide-eyed, "Blake...what the hell did you just say?"

Blake's face practically burst into flames as she took another shaky step back, "I-I didn't- I mean- It just slipped out!"

Adam pointed at the door, "Leave."

"But - "

"Leave. Go home. Drink some tea. Think about what you just said, and then never say it again. Then feel ashamed of yourself because you're a terrible, terrible person." Blake stammered, visibly torn between defending herself and crawling into a hole to die. The fact that she could feel embarassment gave him a bit of hope. Just a bit, "Baka," Adam repeated, staring at the ceiling in disbelief, "She actually said it. Where did we go wrong."

"Shut up!" Blake hissed, practically vibrating with shame.

"Baka," he said again, louder this time, "In Mistralian, no less."

"I'm going home!" Blake finally blurted, turning and sprinting for the exit like her life depended on it. Adam watched her flee, pinching the bridge of his nose as the door slammed behind her. The gym was quiet again, but the damage had been done.

"Baka," Adam muttered one last time, shaking his head as he collected his things, "I need to do something before it gets worse."

Two days later, he registered for MenToo.
