Across the country, baseball is one of the most popular sports that even has dedicated stadiums and fields everywhere. That’s why even in a school not specialized in it a Baseball Club still had a high standing among the faculty and perhaps the whole student body.
Not for me though. If I ever became interested in a sport, then it was because the girl I was targeting was more or less involved with it.
Shizu’s choice to go there personally could be attributed to the popularity of her masked persona. She could act as the well-liked and popular President that could probably intimidate someone if they knew of her identity.
If that didn’t work on the Baseball Club, she would surely not go there blindly without preparing something to protect herself and to make them fall in line.
