The Mini Edgeshot

Tatsuma Ryuko, also known as the pro hero Ryukyu, was unsure what to expect when Edgeshot asked her a favor. 

So here she is, standing in front of Edgeshot's house. She knew very well the pro hero has a mission on the other side of Japan for a whole weekend, but why would he asked her to come here?

"Aah, thank you for agreeing to this favor Ryukyu-san." Edgeshot said, leading her to the living room. "The favor is simple, but something that you must not mention to others."

That got her completely. What would be so simple, yet must be keep as a secret from others? She was about to asked, when a boy came in.

The first thing that came to her mind seeing the boy was: A mini Edgeshot?

"This is my son, Kakashi." Edgeshot said, surprising Ryuko. That would explain why she has to keep this a secret. Edgeshot never told anyone who he is, it was surprising that he even gave her his address.

Egdgeshot left soon after, leaving Ryuko with Kakashi. The boy, who couldn't be older than six, head to his room after staring at her for a solid ten minutes.

Three hours later, not a single peep came from Kakashi's room. Ryuko, whoever, was curious about the boy. Using snacks as an alibi, Ryuko entered Kakashi's room. And promptly gawked at the sight that awaited her.

Kakashi was reading. On the ceiling. He was literally sitting on the ceiling. Kakashi looked at her and raised an eyebrow.

"I-I brought snacks." Ryuko said, placing the snacks on the table. She quickly made her way out of the room and contacted Edgeshot.

Ryuko: I went inside Kakashi's room and your son was reading on the ceiling!

Edgeshot: Oh, that. That's normal. He can do crazier things than that. I swear, the laws of physics seems to not exist with him.

Ryuko felt her eye twitched. What does Edgeshot means it's normal?! And the fact that Kakashi can do crazier stunts with no consequence from the laws of physics?! 

Ryuko's first impression on Kakashi: He might have some vampire quirk mutation.


Sakamata Kugo, known as the Killer Whale hero: Gang Orca, had no idea what lead him to this situation. Sure he owes Edgeshot, but the idea of watching over his kid was surprising.

It was not that he hates kids, quite the opposite in fact. It was just that, most kids were easily frightened with his looks. Regardless, he had agreed to take little Kakashi to the aquarium while Edgeshot takes care of a mission this afternoon.

Kakashi was interesting, to say the least. The boy was not scared of him, he merely took one look and shrugged at his appearance. 

Kugo had no doubt the boy is Edgeshot's son. From the hair to the ninja attire, the boy was undeniably Edgeshot. A mini Edgeshot, you could say.

Kakashi seems to enjoy the aquarium. It was hard to tell, what with the mask and headband covering almost the entire face of the eight years old.

Kakashi had made his way over the next exhibit. It was a dipping pool, one where you can dip your hands or toes with the fishes.

"Gang Orca sir."

Kugo looked at the man who called him by his hero name. The man had a look of admiration. He also has a badge indicating he was an employee

"Can you please sign this."

Kugo spend some time with his fan. He was busy talking to the man, when a loud shout was heard.

"There's a kid who jump on the tank!"

Kugo felt himself freeze. He looked around for Kakashi and didn't saw him at where he was. He head towards the tank that the kid had jumped sweating buckets.

If Edgeshot found out his kid drowned, he was doomed. Nevermind the fact that he was bigger and taller, Edgeshot can assassinate him in a crowd and still get away with no witnesses.

Kugo blinked at what he saw. There was Kakashi, standing on the water petting the fishes. Kakashi was standing on the water.

Maybe he should have asked Edgeshot about his son's quirk.

Kugo's first impression on Kakashi: He could kill someone with his stunts


Kan Sekijiro, also known as Vlad King, wonders why he agreed to this. He promptly remembered owing Edgeshot after he helped him from a gang of villains.

Kakashi was a mini Edgeshot. There were several differences, but Sekijiro can see the connection between Kakashi and Edgeshot.

Right now, he was watching a pre-quirk era anime with Kakashi. Why pre-quirk era exactly, he was unsure. He has to admit, the show is enjoyable. Maybe it has something to do with the fact that it isn't blatantly about heroes. 

Just as the end credits of the first episode appeared, Kakashi came into the room carrying another bowl of popcorn. Wait. Kakashi?!

Sekijiro looked at the Kakashi sitting on the couch with him before looking at the Kakashi who came in. He looked back at the Kakashi on the couch, then back to the Kakashi who came in and was now chewing presumably some popcorn.

The Kakashi sitting next to him suddenly turned to smoke, and the Kakashi carrying the bowl sat down on his-its(?) spot. 

Kakashi looked at him and moved the bowl closer to Sekijiro. "Want some?"

Sekijiro's first impression of Kakashi: Edgeshot didn't warn him about this.


Iida Tensei, also known as Ingenium, was unsure what to think of Edgeshot's favor. On one hand, he greatly admired and also owes the pro hero, on the other hand, he has to watch a kid the same age as his younger brother.

Kakashi is the opposite of his brother. Laidback, seemingly lazy, and carefree attitude, Kakashi was nothing like Tenya and more like Tensei.

Both of them had taken to playing an old racing game that was popular back in the pre-quirk era. Despite being super fast in real life, Tensei was losing at the game.

Kakashi won the game for the eight time in a row. Tensei was starting to think he was cheating. 

"Maa, another round?" Kakashi said, giving him an eye smile.

"Sure, MiniShot." Tensei replied. The kid is adorable.

"Maa, I'm gonna get a drink first." Kakashi said, before disappearing in a puff of smoke. Tensei blinked once, twice, three times to make sure he didn't imagine that.

A puff of smoke and Kakashi was back. He gave Tensei a side glance before grabbing the controller.

.

Tensei set down the bowl of ramen for Kakashi. He has no idea why the boy asked for ramen for dinner. Edgeshot would be back in an hour.

Tensei eyed Kakashi, confused on why he hadn't removed his mask yet. He only blink once, and Kakashi's bowl was empty. Not only that, but Kakashi was chewing despite still having his mask on.

Tensei's first impression of Kakashi: He really is a ninja.
