|“||His play-style is not flashy by any means but rock-solid.||”|

Relationship with other charactersEdit
After confirming Miyuki's injury Kuramochi approaches Shirasu first and they both prioritize Miyuki’s well-being and vowed to stop him if it all goes wrong, even if it means diminishing their chances of winning the tournament and make Kataoka stay as their coach.
Shirasu acknowledges Miyuki's skills as the "pivotal part of the team". After Kuramochi told him about Miyuki's injury he realised anew how much Miyuki's existence means for the team and that they took his abilities granted way too much. He describes Miyuki as someone you can't imitate no matter how hard you try, because he is the captain, the fourth batter and someone who participates in one match after another (that alone is something really amazing). Shirasu (and Kuramochi) were clearly worried about Miyuki during their match against Yakushi High School.
Shirasu is known as a reliable defender. He can see through batters' defining features and adjusts his position in defense accordingly. Harada had described Shirasu as the most balanced hitter in Seidou's lineup, having great speed while also being able to hit for power.

- "Wow! I saw something totally awesome! From up close!" - Sawamura
- "It's reassuring to know he's defending behind you because you can't find a person more reliable."
- "He's someone to look up to as an outfielder." - Toujou
- "When I heard Kuramochi say it, it dawned on me anew... just how much that guy's existence means for our team. "If it;s him, he can do it." "If it's him, he can hit it." And never once had it occurred to us that we took him and his abilities for granted way too much. If Miyuki can't continue playing in this match... Participating in one match after another. Just that alone is already something amazing. Not to mention he's the captain and fourht batter now. Someone you can't imitate no how har you try... At the very least, I want to show my gratitude trough contributing with my play." - about Miyuki
