Rei is enjoying a big feast with the Kawamotos before he heads off to Osaka for the Newcomer Tournament final, but Hana isn’t. She can’t eat a bite; her stomach hurts. It’s because she’ll be heading off too: to Kyoto, on a multi-day class trip.
Rei immediately knows why Hina is feeling the way she is, and gives what advice he can to help ease her pain, since he’s felt it too. He vividly imagines the hell she’ll have to face while on the trip, ostracized by her peers. She’s going into battle just as much as he is. And like him, she wants to win.
When Rei meets Kawasaki Junko, the game records of his semifinal match with Nikaidou have already said a lot about the guy (except that he looks really old for someone 26 and under). Knowing he couldn’t beat Nikaidou in a quick game, Kawasaki did everything he could to lengthen it, knowing Nikaidou’s health would give out and the match would be his.
Knowing this is how Kawasaki wins fills Rei with rage, and he almost plays right into his opponent’s hands when a voice inside him stays his hand: it’s Nikaidou’s words ringing out: don’t attack, defend; take care of your shogi and yourself. Perservere. It’s what Nikaidou did, even though he failed. It’s what Hina is doing in Kyoto.
Back on course, Rei contains his anger and focuses it on persevering, on enduring the mind games Kawasaki is playing, and by focusing on the shogi, and when the match is over, Rei is the new Newcomer King, while Kawasaki is a fief in the land of losers where he deserves to be for his callus, unchivalrous play.
Rei does not savor the victory long, because he knows Hina’s still out there battling. After a fellow player gives him some stomach medicine Shimada recommended, Rei races to Kyoto by bullet train, and using Hina’s class trip schedule, combs the shopping venue where her class is supposed to be.
Then he remembers his own times of loneliness during such trips, and how a mall full of laughter and fun would be the last place he’d be. Instead, he searches the river, the place back home where she’s always run to be alone.
Her reaction to Rei suddenly appearing there, just when she was about to start crying, is hard to put into words. Poweful? Sure. Heartlifting? You bet. When he was younger, Rei had to face many battles alone.
Now he knows how much better he’d have fared if he had someone beside him to make things even a little more endurable, and happens to have someone in Hina who he can ensure won’t endure her battles alone.
All it took was being there—in that particular time and place—to be hugged, to be a font for her tears, to remind her she isn’t fighting in vain, and that it’s going to be alright.
