Maruo's America arc strips away the safety net of being a prodigy in his own country. He's suddenly the student again, grinding through matches where he loses as often as he wins, and the show lets those losses sit with real weight instead of rushing to redemption. Tennis becomes the honest mirror it always was, but now he's finally old enough to understand what he's seeing in it.
Eiichirou lands in America ready to prove himself on the international tennis circuit, but the reality hits fast. The competition here operates on a different level entirely, and his carefully developed techniques crumble against opponents who've been grinding since childhood. Every practice match becomes a humbling lesson in how much further he needs to go. Separated from home and the familiar comfort of his support system, Eiichirou confronts not just stronger players but deeper questions about his own limitations and potential. His methodical approach to improvement gets tested by rivals with raw talent he can't match through hard work alone. Yet each loss and setback becomes data, fuel for the next iteration of his game. What keeps him grounded is the connection pulling him back home, a reminder of why he's chasing this dream in the first place. America forces him to grow up fast, pushing past the safety of incremental progress into genuine hardship. This is tennis without a blueprint, where instinct and adaptation matter as much as analysis.
