When Yagi Toshinori first met Midoriya Izuku, he thought nothing much of the boy. He seemed like a normal child, albeit a bit more nerdy than most. Soon, Toshinori found that the boy was also more stubborn than most, clinging onto his legs when he jumped.

When the boy first admitted that he was quirkless, Toshinori felt for the boy, but there was nothing to do about it, and crushed the boy's dreams of being a hero, telling him not to chase a fool's dream.

It wasn't until when the boy attacked the slime villain without any hesitation just to rescue his classmate that he really looked at the boy. Despite his unnerving silence and smile, there was something about the boy that made Toshinori smile. Making up his mind, he decided to make the boy his successor.

Maybe it wasn't the best or sanest decision he could've made, but he wasn't going to change his mind. In the past, Nana had called out his stubborn, bullheadedness, but Nana wasn't around anymore and Gran Torino didn't talk to him much either, so there was no one to call out his rash decision making.

"I want to make you my successor."

"...What."

"My quirk, One-For-All, can be passed down. It's nearly time for me to pass it to the next generation, and I've decided who."

"...Me. You want me to receive your quirk?"

"Yeah, kid. Do you accept?"

"...Okay. I-I'll do it."

(Humans are such strange creatures. A quirk that can be passed to another... It sounds familiar, but I can't put my finger on it. Oh well.)

When Toshinori first started training the boy (Midoriya-boy), he had only expected a child with average strength, stamina, and energy. What he did not expect was the boy to be not only quirk-leveled strong, but fast as well as well as had plenty of energy and stamina. Had he not looked at the boy's files, he would have thought that he was lied to because of Midoriya's immense strength.

Not only that, the boy was extremely quirky. Midoriya was probably one of the most unique people that Toshinori had ever met and even that was an understatement. On occasions, the boy would seemingly read his mind or just blurt out random facts that had caught his interest that day. Toshinori also quickly found out how stubborn the boy was.

One day, Midoriya asked him what his real name was and when Toshinori avoided the question, the boy spent the next week and a half pestering him until he finally gave and told him his name.

"Neh, All Might-san!"

"Hmmm?"

"What's your real name?"

"*Cough* *cough* W-where did that come from?"

"Ah. You have blood all over you again. I was just wondering. It's a bit of a pain to call you All Might all the time even when you're in your real form. Hence, I should use your real name~"

"...Midoriya-boy, have you finished cleaning up that area yet?"

"...Avoiding the question, eh? Oh well. You'll tell me eventually, right~?"

Despite the boy's quirky behavior and strangeness, Toshinori couldn't help but develop a certain fondness for the boy. So, when it was time for Midoriya to receive his quirk, he felt absolutely no regrets.

Of course, that meant he was immediately filled with worry when he watched the small boy be overwhelmed during the fighting portion of the exam. It was a harrowing experience for the gaunt man who had come to care for the child over the course of the summer vacation.

Smiling slightly despite his worry, Toshinori watched as Midoriya saved the girl from the enormous robot, only to be injured. It calmed his heart to know that despite the boy's dark and mysterious nature, he still had it in him to save another, proving that he had a hero's mindset.

Watching the other children, he grinned slightly. It filled him with hope and happiness when he watched the future generation of heroes fight. One boy in particular caught his attention. Bakugou Katsuki.

While he had seen Bakugou and Midoriya interact a lot outside of class, their relationship baffled him, as well as several of the other teachers that taught the duo. It wasn't until the battle trials that he had a deeper insight of Bakugou and Midoriya's relationship.

"Hey, Izu."

"Hmm?"

"I'll prove to you that I don't need protecting."

"Kukuku... Of course, Kacchan~"

"Goddammit! Izu, I'm being fucking serious! You better take me seriously as well!"

Everyone kept their eyes glued to screen as the smaller boy smirked.

"Uraraka-san, I'll deal with Kacchan. Go ahead and reach the nuclear core and Iida-kun."

Uraraka nodded in agreement and rushed past the explosive boy.

"Now~ Kacchan~ It's just you and me~"

Bakugou grinned.

"Fuck yeah!"

After Bakugou and Iida's loss, Toshinori had expected anger or disappointment. What he had not anticipated was for neither party to have hard feelings. With Bakugou's personality, he had thought that there'd be a grudge, but Toshinori noticed that the boy seemed to have already expected the outcome.

When he questioned Bakugou about the subject, all he got was somewhat more polite version of 'fuck off,' but with Midoriya... Well, it was interesting. After spending all of the summer with the boy, he had known about his cryptic and nonsensical answers, but what he got was completely ridiculous to the point that he just gave up and pushed his curiosity to the back of his mind for later.

Of course, when USJ happened, his curiosity could no longer be contained, especially with the confusing and incriminating scene in front of him. He had expected a lot of villains and even a heavily injured Aizawa-kun. What he did not expect was what he saw.

Frozen from shock, he watched as a somewhat flustered Midoriya cradle an injured Aizawa-kun. In the background, he could hear the other heroes and students approach the clearing to see what was going on. A couple seconds later, he heard laughter coming from one of the students.

"Don't worry, All Might-sensei... I'll explain everything, so please, let's get the youngling to safer place first."

"Youngling?"

"Oops... I mean Aizawa-sensei."

"Just what are you?"

So many unanticipated events... I hadn't expected for this man to approach me. I didn't expect him to offer his quirk to me. I didn't expect him to remind of that person or going to UA. I didn't expect to meet with the youngling or have to protect him. So many unexpected things... How amusing~

Yagi Toshinori. Thank you for reminding me of why human legends are made. I certainly will not be forgetting you for quite some time, or even ever.

"Me?"

"...I simply am a vampire."
