Sometime after saving the world for the 87th time that week, Saitama discovered a new, deeply heroic passion: collecting stuff.
Not powerful stuff. Not rare weapons. Not even coupons (though he respected those). Just… stuff.
It started with supermarket stickers. "Buy 10 cabbages, get 1 free sticker," the cashier said.
Saitama stared at the tiny smiling cabbage sticker like it held the secrets of the universe.
"…I need all of them."
Soon, his apartment looked like a museum curated by a very confused raccoon.
A shelf of slightly different instant noodle lids, A drawer full of loose buttons he found on the street, 37 identical pens that didn't work.
One rock he labeled: "Good Rock (Round)"
Genos walked in one day, paused, and scanned the room. "Sensei… is this a new training method?"
Saitama, crouched on the floor, carefully placing a bent spoon into a shoebox, replied "Yeah."
"…What does it train?"
Saitama held up the spoon like a sacred artifact.
"Commitment."
Things escalated, he began hunting for rare finds. Not villains or monsters, but limited-edition grocery items.
One day, he burst into the Hero Association HQ."Emergency!"Everyone panicked.
"What is it?! A Dragon-level threat?!"
Saitama slammed a flyer on the table.
"Limited-time tofu packaging. Only 100 made."
Silence. Genos leaned forward seriously, "We must act quickly."
Meanwhile, King visited Saitama's apartment. He stared at a glass case in the center of the room, inside… a crumpled receipt."…What's this one?"
Saitama spoke in a hushed tone."Final discount receipt. 90% off. Legendary."
King nodded slowly,"…I can feel the power."
Eventually, a monster attacked the city. A giant creature made entirely of scrap metal roared:
"I AM THE COLLECTOR OF ALL THINGS—"
Saitama's eyes lit up,"…Collector?"
Five seconds later:
One punch.
The monster exploded into a pile of junk. Saitama gasped"…Whoa."He immediately pulled out a plastic bag.
"Jackpot."
Back home, he added a twisted piece of metal to his shelf.
Label:
"Monster Scrap (Cool Shape)"
He stepped back, arms crossed, proud
"…Man."Pause"…I should get more shelves."
And somewhere in the city, villains whispered in fear:
"Beware the bald hero…"
"…He doesn't just defeat you…"
"…he organizes you."
