Chapter Text
The first time Seidou realized Sawamura Eijun was basically a walking encyclopedia, it was over something extremely stupid.
“Hey, Sawamura.”
“Yeah!"
“Why do onions make you cry?”
The entire room immediately looked at Kuramochi who asking Sawamura,look like expecting an stupid expression on Sawamura.Try to tease him with his hyena laugh.
Sawamura blinked.
“Because when you cut them, they release sulfur compounds that turn into a gas that reacts with your eyes’ moisture to form a mild acid.”
Silence.
Kuramochi froze.He did not expect an answer that fast from him or that Sawamura will answer it.
“…That was too fast.”
Sawamura tilted his head. “You asked.”
“I didn’t ask for a CHEMISTRY LECTURE.”
Miyuki, without looking up from his phone, muttered, “You literally asked for science.” Smirking.
From that day on, Seidou started treating Sawamura differently.
Not as a pitcher.Not as a teammate.But as a resource.It began with Haruichi.
“Uh… Eijun kun, what’s the capital of Kazakhstan?”
“Astana—wait, they renamed it Nur-Sultan for a while, but I think it changed back again.”
Haruichi slowly closed his notebook.
“…Why do you know that?”
Sawamura grinned. “It came up in a book I read once.”
Miyuki looked up.
“That’s not normal reading material.”
“It had maps!”
Then came Kanemaru.
“Sawamura, why does metal feel colder than wood?”
“Because metal has higher thermal conductivity, so it draws heat away from your hand faster."
Kanemaru stared.
“…I regret asking.”
“You shouldn’t ask if you don’t want answers!”
“That’s not how QUESTIONS work!”
Eventually, it escalated.Seidou stopped asking Google.They asked Sawamura.
“Hey, Sawamura, how do you tie a knot properly?”
“Hey, Sawamura, why do muscles cramp?”
“Hey, Sawamura, is it safe to eat this?”
“NO. DEFINITELY NO.” (That one was important.)
Miyuki finally drew the line when Sawamura started answering things before being asked.They were reviewing footage.Sawamura pointed at the screen.
“That batter has a slight delay in his hip rotation when he’s expecting an outside pitch.”
Miyuki paused.
“…I was going to say that.”
Sawamura blinked. “Sorry?”
“No, don’t be sorry. Be… less accurate.” Other wise you will no longer our resident idiot.Miyuki thought.
Chris, watching quietly from the side, finally said it out loud.
“He’s basically our team’s encyclopedia."
Kuramochi groaned. “More like a cursed search engine with legs.”
Sawamura beamed. “I like that!”
“No, don’t encourage it!” Say Jun san.
The final confirmation came during a rainy practice day.The team was stuck inside.Bored.Restless.
Dangerous combination.Miyuki tossed a random question out of frustration.
“Why do we get déjà vu?”
Sawamura didn’t even hesitate.
“Likely due to a mismatch in short-term memory processing where your brain incorrectly flags a new experience as a stored memory."
Silence.Rain outside.No one spoke.Then one by one asking Sawamura a question which he answered all correctly.Then Kuramochi stood up.
“Okay. That’s it. I’m not losing arguments to a pitcher anymore.” Kuramochi choke hold Sawamura.
Sawamura looked offended. “You were losing anyway!” while try to get away from his hold.
From then on, Seidou officially changed their system.
Need baseball analysis? Miyuki.
Need discipline? Coach Kataoka.
Need survival advice? Chris.
Need violence? Kuramochi.
Need black material?Ryousuke.
Need literally anything about the universe?
“…Sawamura.”
Sawamura, already smiling: “Yeah?”
And just like that, Seidou had their own walking encyclopedia.
Loud. Chaotic. Unfiltered.
But terrifyingly well-informed.
And somehow, the most dangerous thing about him wasn’t that he knew everything.
It was that he was still curious enough to learn more.
