4 Days Later:

Izuku was carrying 4 black trash bags, 2 in each hand, as Kakuzu was throwing green bags into the back of a truck. Izuku was having a little trouble holding the pebble on his head, but at most, he could hold on there for 20 seconds. As he took another step, the pebble fell off his forehead and fell onto a clean section of the beach. Kakuzu turned around and saw the pebble on the sand as he grabbed a pebble of his own and flicked it at Izuku, hitting him in the forehead and sending him falling to the ground. Izuku dropped the bags he was carrying as he held his forehead, "Ow! Why did you do that? I thought you said you were going to hit me?!" Izuku cried, a small trickle of blood going down his forehead

"I was feeling lazy. Now get up and try it again," Kakuzu ordered, watching as Izuku got back up, placed the pebble back on his forehead, and picked up the bags. Slowly walking to the truck, Izuku tossed them into the nearby dumpster as Kakuzu closed the lid, "Dumpster's full, start collecting recyclables," Kakuzu pointed at the plastic and metal

"Y-yes, sensei," Izuku nodded, going back to collecting things on the beach

"What did you call me?" Kakuzu raised an eye-brow. Izuku felt a shiver go down his spine as he turned around, "What. Did. You. Call. Me?" Kakuzu slowly repeated

"I-I called y-you s-sensei, i-is th-that al-right?" Izuku stuttered, scared of what's about to happen next. Kakuzu glared at the young boy until he turned his head and closed his eyes, "Get back to your training," Kakuzu mumbled, walking over to an old fridge and pulling the back off of it. Izuku gave a sigh of relief as he continued cleaning up the beach.

Meanwhile:

Inko was sitting on her couch, her eyes were lifeless and puffy from all the crying she had been doing since her son was taken away. Her clothes were dirty as she'd only worn them for the past few days. As she sat on her couch, still crying silently, she heard a knock on the door, "Inko? Are you there? It's me, Mitsuki!" a voice called out

"C-come in," Inko managed to say as her friend, Mitsuki came through the door. Mitsuki walked through the door, she wore a light-purple blouse with a white shirt underneath, a skirt, and sneakers, "Hey, Inko! I haven't heard from you in a while a- Inko?" Mitsuki inspected Inko, looking at her condition. As she got closer, she put a hand over her nose and said: "Holy shit! You smell like hell!"

"Oh, I-I do,s-sorry," Inko mumbled as Mitsuki looked around the room

"What's going on? Where's Izuku?" she asked, making Inko's lip tremble. Inko started crying again, saying: "My baby boy's gone!"

"What do you mean Izuku's gone?!" Mitsuki shouted. Inko pointed to his bedroom as the blonde ran to the room to see it in disarray, "WHAT THE FUCK?!" Mitsuki screamed, shaking the entire building, "WHAT THE ABSOLUTE FUCK HAPPENED HERE?!"

"I-I do-don't know. I-Izuku c-cam home, t-then a-awak-ened a q-quirk. T-Then a-a man c-came-a-and took him away!" Inko cried, burying her face into the couch, muffling her wails. As Mitsuki looked back and forth between Inko and the room, Mitsuki gritted her teeth as she bawled her fists, "Inko, I'll be right back," Mitsuki growled, walking out of the apartment.

Several Hours Later:

Izuku was lying on his back as he held a green bag in his hands. Kakuzu was standing over him as the ladder looked down with a sneer, "Come on, brat, get up. It's the end of the day. Just toss that bag into the truck and you'll be done for today," Kakuzu said, this caused Izuku to grit his teeth and perform a curl-up. With the bag in hand, Izuku managed to stand up and toss the bag into the back of the truck, "I-I did it," Izuku whispered as he heard a coo behind him. Izuku turned around to see Kakuzu with a pigeon in his hand, "What's with the bird?" Izuku asked as Kakuzu unwrapped a piece of paper from the bird's leg

"Another mission," Kakuzu said, "5,000,000 for a banker... hmm, I could use this to my advantage,"

"5-5,000,000?!" Izuku shouted

"Well, looks like we've got to make this quick. Hop in the truck, we've gotta dump this off and then you're coming with me on the job,"

"Ehhh?!"

"Truck! Now!"

Later:

Kakuzu was counting the money he got from recycling and what gold and copper wire Izuku found on the beach. Izuku was napping in the passenger-side front seat as Kakuzu sat next to him. He looked at Izuku and then at the glove-box. Putting said money in the glovebox, Kakuzu started driving to the location of the job. The sun was setting over the horizon as he drove through the empty streets of Musutafu. Stopping at red-light, Kakuzu saw Izuku shiver a bit, making Kakuzu growl, "Stupid brat," Kakuzu whispered as he pulled out a small blanket from under his seat and toss it on the boy. Looking at Izuku, he could only sigh as he whispered to himself, "Sensei... bah, what a stupid thing to call me,"

Flashback:

A young Kakuzu sat in a classroom. He inspected the forehead protector he got from graduation as he smiled, "Finally! I get to be a ninja!" Kakuzu said in excitement as he tied it around his head

"Alright class, since we're in the middle of a war and we have able-body ninja, you'll be placed in teams of two. One Jonin and one genin. I'll start naming you and your sensei's off," Kakuzu's homeroom teacher said as he started naming off his class-mates. Each one left the room, one by one, until he was the last. He sat at his desk, his green-blue eyes looking at his sensei, "Sensei? Where's my Jonin?" Kakuzu asked

"Kakuzu... you're actually a special case. Someone asked for you personally," he answered as there was a knock on the door, "come in."

"Sorry I'm late, I had to drop off a few things before I came here," a man said as he came into the classroom. He was a tall man, standing 6' 2" with tan skin and dark-brown hair. He wore black pants with a long-sleeved shirt under an armored vest. His headband was tied around his left shoulder as he tapped the floor with his combat-boots. The man looked around and saw Kakuzu sitting alone at his desk, "Hey, kid, you're Kakuzu, right?"

"Y-yes, sir!" Kakuzu answered, standing up with a salute

"At ease, kid. Come on! We're going to the bounty board," the man ordered asKakuzu nodded

"Y-yes, sir," the young Kakuzu nodded as he ran to his Jonin-sensei

"Sir? You make me sound old, call me Joshin-sensei," Joshin said with a smile

"A-alright, Joshin-sensei," Kakuzu bowed, following the Jonin out of the school, "see you around, Kosei-sensei!"

"See you around, Kakuzu!" Kosei said as he watched Joshin and Kakuzu leave.

End Flashback:

The old ninja sighed as the light turned green and he started driving down the street. Making a left, and then a right, he drove right past a pair of people shouting kami-knows-what and started going faster, their shouts still being heard from a distance.

"Izuku! Izuku! Where are you!?"

"DEKU! GET YOUR ASS OUT HERE!"

*THUNK*

"AND THIS IS WHY YOU CAN'T HAVE NICE THINGS!"

"SHUT THE FUCK UP YOU OLD HAG!"

"Dear kami," Kakuzu whispered to himself as he continued driving.
