The hour expires

Kendo and Yanagi stood at the entrance to the Ruins Zone. "They do know how to get back, right?"

"Is it possible that Setsuna performed the impossible and managed to overpower Midoriya?"

"Not to downplay Set, but I doubt that." She looked to the zone's exit with intensity. "He's faced down each member of the league of villains, and not only lived to tell the tale but helped arrest a member or two. He could probably take all three of us down if he really had to."

"So you believe Midoriya didn't treat us like true threats?"

"Or he didn't get the chance." Kendo then looked over to see Izuku walking to them while giving Setsuna a piggyback ride.

"Hey..." Izuku said somewhat shamefully. "So, her plan worked."

"What?!" Kendo yelled.

"Even when playing the villain, poor Deku can't stop himself from being the hero," Setsuna said with a smirk.

Izuku nodded. "She figured out I wouldn't go full speed with my quirk if I thought she wouldn't hold on."

"Used his hero instinct against him... yeah, that'd do it. Now get down, Set." Izuku bent over for her to get onto ground level, but she was rather **** to do so. It was only when Kendo began to approach her she dismounted. "Good girl."

"As for our proper objective," Yanagi piped in, "Some small robots shall soon activate and simulator trapped survivors. We are to then work together and rescue all 4."

"He's really trusting us, huh?" Or the Sex Note things this is the best way to get perverted situations to happen. "Okay, here's the plan: Yanagi and I will cover the left side, Kendo and Set get the right. This work."

"I find this reasonable," Yanagi said, while Kendo gave the thumbs up.

"Aww..." Setsuna said, "I was really hoping to pick up where we left-"

"Setsuna, I'm not joking," Izuku said sternly. Despite being shorter than Setsuna, she took a step back and saluted him: military style. "Good, you ready?"

"Sir, yes sir!"

Kendo leaned over to Izuku with a grin. "I might have to consider keeping you around."

Izuku paid that thought no as Yanagi hopped on his back and he zoomed off.

Yanagi, walking on her own two feet, started to lift rubble with her quirk as they heard faking crying from one of the robots. No wonder she was placed here, loose debris like this makes her suitable for rescue and combat. Actually,I'm kinda glad Setsuna kept me from going after them now. Having to constantly blast rumble apart doesn't sound like a great time.

"There we go" she held up the egg-shaped robot. "Head to the entrance, it's safe there."

"Understood," it said flatly as it grew propellers and flew away.

"That should cover our obligation for the assignment. Shall we meet at the front entrance?" Izuku smiled and nodded, happy that their half didn't take too long. "We still have half an hour left, Midoriya. How are we to occupy our time?"

"Not sure." Izuku walked forward. "This training seems a little relaxed, but I guess with it being last minute and all-"

"It is?"

Izuku gulped. "Uh, uh, I heard Mr. Aizawa say so. Most of my class was too busy talking, so I don't think anyone else paid attention to that part."

"You keep an ear out, don't you?" Her smile convinced Izuku to calm down.

"So, how does your quirk work?"

"Ah, well, my quirk gives me unfettered control of anything," A rock on the ground became purple as she lifted it up, "however, my will must be stronger, or so my effect on humans is quite limited."

"Oh?"

Yanagi nodded. "Most people's focused willpower is enough to break my quirk as it is. Only if they completely submit to it, or if their will is heavily divided can I actually take possession of their body or mind."

"Wait, mind? So... is mind control part of your quirk?"

"There is a real possibility of that, but it lacks any practicality in a realistic scenario. So far, I've been able to lift Nieto's body after Kendo knocks him out with her impressive martial arts neck chops, so it appears I can pick up an **** person, although that's about as heavy as any one possession can get." Yanagi then rubbed her legs together. "Any mind control results are limited to when Setsuna splits her body parts; her willpower is split up between them, leaving her mind up to manipulation."

"Uh..." Izuku wasn't sure he was meant to hear that.

"Oh!" Yanagi turned red. "I assure you I've done nothing illicit or shameful!"

"No, no! I believe you!" Izuku recomposed himself. "Sorry, I didn't mean to insinuate anything. And honestly, most forms of telekinesis is really cool, but it sounds like yours is really pro material!"

She muttered out a "Thank you." A few moments of silence followed, but the Note soon moved Yanagi's hand. "Midoriya... may I ask for something... embarrassing?"

Izuku didn't answer right away, but did manage to say "sure" shortly after.

"Well... how comfortable are you in let's say an..." Yanagi gulped really hard, "intimate situation?"

Izuku once more didn't answer, but instead gulped himself. Yanagi took that as a sign of nervousness when it was him knowing the long-term implications of what's going on. "Depends." was all he answered with.

Yanagi pulled her mask down "Just... just a kiss?"

"Oh." Izuku calmed down a little at the idea of that being as far as it goes. "Yeah, that's not the worst."

The ghost girl nervously laughed. "I'm merely curious if my quirk... would have any effect? If that could divide one's attention enough?"

Despite his legs shaking from the fact another girl was, in a sense, coming on to him, the idea of helping her get a better grasp of her quirk gave him the confidence to say "I'll help" without hesitation.

Both quickly looked around to make sure they were alone (they were), and both put their arms around the other's necks. Izuku's experience seemed to have taken Yanagi by surprise, but she wasn't bothered otherwise. A few seconds in, Izuku heard a voice in his head giving him a command. "Grope me, Midoriya." The strange part was that it was in his voice, but not in his usual inflection. The command started to repeat a few times, getting more forceful. As Izuku got annoyed, he realized this was Yanagi's quirk at work. Eventually, Izuku did comply simply to stop hearing it; he found her moans to be generally better.

Upon separating, they both looked at each other in silence. The two sat on the ground beside each other before she said "It worked, huh?"

"Uh..." He wasn't entirely sure how honest he should be, but lying wouldn't help. "I don't think so."

"But-" Yanagi looked around in every direction to make sure there wasn't a Setsuna part floating somewhere "-you did exactly what I said to."

"Yeah, but it was by choice," Izuku said. Yanagi looked down in a bit of shame, so he instinctively placed his arm around her. "You okay?" She nodded but didn't speak nor look at him. Izuku let her lay her head on his shoulder. Now that I think about it... I should have known that was her. Why would I refer to myself by last name? In fact, it took me getting annoyed at me commanding myself to be piece that together. And I was warned ahead of time. It's actually like the opposite of Shinso's quirk; my mind was getting ideas I thought were my own, but I had control of my body... Wait, that's it! "Hey, Yanagi, I think I know how that part of the quirk works!"

"Yeah?" She said in a drained voice.

"Okay, hear me out." Izuku got her to sit upright as the two looked at each other. "Your quirk is telekinesis, or a version of it, right?" The spooky girl nodded. "Okay, so I noticed that, despite knowing what you were doing, your quirk seemed to stop me from picking up the thought wasn't mine." And One For All probably gave me an advantage in that regard "If your quirk is about putting suggestions, maybe you don't need control people, just being their inner voice?"

Yanagi paused to give his idea thought. "You might be on to something. I doubt I could test it on you reliably, though."

Izuku thought for a second before snapping his finger. "Hey, I got an idea."

////////////AN/////////////////

So I played a bit with Yanagi's quirk. The wiki itself mentions that the limits of it, and even the exact nature of it is. I assure you that, if I continue this route long enough, her quirk will be revisted.
