Forever His

Sensitive Mother Trucker -5-

"Oh dear." Recovery Girl muttered after she had kissed Izuku on his forehead and wiped the blood away. "What happened?" Keigo asked worriedly. "Midoriya's quirk. He hasn't been properly trained with it, as many students here. Not expecting the noise and not knowing how to handle it, his quirk heightened his senses accidentally." she explained.

"I don't get it." Keigo muttered. "His quirk. It heightens his senses on command. However, unless properly trained, they will go haywire. Here, his fight or flight instinct kicked in." she explained further. "Thankfully, his quirk didn't overdo it, and that you brought him when you did." she said quietly. Izuku came out of a changing room in a new change of uniform. His got blood over it so he needed to change.

"What would have happened?" Power Loader asked softly. "He could of had his hearing damaged, enough to where he needed hearing aids, or needed his quirk helping his hearing 24/7." she explained sadly. "Why did you tell me?" Keigo asked Izuku. "It's just some weak quirk." the green and black haired boy muttered. "It's not weak." Recovery Girl told him. "Your quirk could be very useful for a hero. You just need to be trained." Power Loader told his student, attempting to lift his spirits. "It's alright. I gave up that dream a long tome ago." he mumbled.

"Why?" Keigo pressed the taller male. "Doesn't matter." Izuku said while straightening up and running a hand through his hair. "Thank you for healing me Recovery Girl." he told her before turning to leave. "You should head back to your classroom." Power Loader told Keigo. "I'll write you up a pass." Recovery Girl said before scribbling something down and handing him a piece of paper. Keigo just stood there, thinking about what could possibly make his Izuku give up on his dream.

Keigo quickly thanked her before walking off to his own classroom, both Power Loader and Izuku long gone. On his way there, he thought about what or who would make Izuku give up on being a hero. Who would do that? His quirk is amazing and couple be so so helpful if he was trained. Hell, he could be pretty much anything he wanted!

He was pulled out of his thoughts when he realised that he had reached his classroom. He opened the huge door and stepped in. He closed the classroom door behind him and walked over towards his teacher, Aizawa. "Where were you?" the tired teacher asked.

"Sorry sir. I was with Izuku Midoriya from the support department. He was injured so me and his teacher had to take him to Recovery Girl." I apologised. He nodded before yawning. "Got a pass from her?" he asked. He nodded and uncrumbled the paper that he didn't realise he even crumbled up in the first place. He handed it over to which Aizawa read it and nodded. Keigo then went over towards his seat behind an angry pomeranian.

"Tch. The damn nerd got hurt?" Bakugo scoffed. "Weak." he muttered under his breath. Keigo just wanted to snap his neck right then and there. His Izuku wasn't weak. Not at all. He was the strongest guy he knew. I mean, if you saw his muscles, you would agree too. Keigo snapped out of it when he heard his friends walk over.

"So you were with Midoriya, huh?" a purple haired boy, Hitoshi Shinso, said in a teasing voice. "S-shut up!" he stuttered out, his face flushing a deep red. "How was he injured?" his other friend, Fumikage Tokoyami, asked. "Apparently his quirk heightens his senses. During that alarm, his quirk turned on and his hearing spiked, causing his ears to bleed." Keigo explained, his blush dying down ever so slightly. "So somewhat similar to my quirk?" a purple haired girl named Kyoka Jiro asked.

"I dunno. I just know that it heightens his senses." Keigo said softly. "Tch. The damn nerd's got a weak quirk that he can't even handle himself." Bakugo butted in. "Shut up." Keigo said quickly, getting all defensive. "What. Do you have a crush on the nerd or something?" he joked. "Bakugo. Back off." Shinso said lowly. "Pft. Fine. But, I guess Deku's not the only faggot in school." he muttered before turning away. That got Keigo pissed.

Yet again, he wanted to just hurt the blonde, spiky, red eyed bully named Katsuki Bakugo. He wanted to snap his neck, slit his throat, stab him multiple times, drown him, torture him, pierce him with his feathers, fly up high and drop him, push him off of UA. Anything that would result in his demise. But of course, unless the wing quirked boy wanted to be caught and arrested, resulting to him being taken away from his Izuku, he couldn't.

He had to just settle with glaring for now.

so an explanation to Izuku's quirk

What it does is on command he can heighten his senses. But when overwhelmed, they can get out of control, causing his quirk to heighten them without him realising.

That goes with his eye sight to where he could even see in the dark, his hearing to being better than an animal's. He senses of smell to be as good or better than a trained dog's would be (ya know like those dogs that can sniff out bombs, track people, that type) His taste sense can be heighten to where he can tell about every ingredient used in a food. He can also heighten his pain tolerance

Stuff like that.

Now some drawbacks to it being, when not properly trained, it can get out of control. He could accidentally heighten his hearing too much and lose hearing permanently (going deaf), becoming blind (permanently), losing sense of taste, etc. He could also accidentally heighten his pain sensitivity instead of heightening his tolerance

He won't be able to do too much with his quirk unless properly trained or with practice.

Also, another thing about his quirk, he can overwhelm someone else's senses through physical contact. He can heighten either someone else's pain tolerance, heighten their pain sensitivity, heighten their sense of smell, sight, hearing etc. The longer he uses it on someone else, the more likely his own senses can get out of control.

I hope the explanation made some sense. Ask any questions about the story or his quirk!
