Stardew Valley, but Rikkaidai
A new student, only 12 years old, arrived at the Rikkaidai tennis club.
His origin, identity, and past records were all unknown on the admission form. All that was known was that he was male, taciturn, and his behavior was... extremely peculiar.
This included, but was not limited to, dark crawling during the club initiation and lifting the hat of the "Black-faced Emperor" Sanada in front of everyone; walking normally before suddenly teleporting into a trash can, expressionlessly rummaging through garbage and stuffing items into his pockets; and half-way through a conversation, pushing open the door and leaving without looking back. When chased, he was found squatting in a flower bed, watering vegetables with a small kettle.
"Wait, where did the vegetables come from?!"
This unyielding and seemingly illogical junior once gave the entire Rikkaidai group a huge headache. But soon, they were surprised to discover that the headache was only temporary; being traumatized was eternal!
After all, this junior simply couldn't be viewed with normal human thinking! #DidYouHearI'mAPlayer #Didn'tHearMeI'llSayItAgainI'mAPlayer
*Prince of Tennis + some Stardew Valley settings + Fourth Wall Break
*Chaotic evil, comedic, fun-loving player, all friendships are of the (traumatized) kind
*Rikkaidai 16+3, Rikkaidai special, low competition, main focus on daily life
Yagikei the player is worried about you, the player chews bubblegum, the player rummages through trash cans, the player makes mistakes and doesn't correct them.
Synopsis: Great, it's a player! We're doomed!
Themes: When interacting with others, honesty is paramount.
