In middle school, he was in a senior league and formed a battery with Haruna (one year older, currently at Musashino Daiichi). However, Haruna was a selfish pitcher who ignored Abe's signs.

That experience became a trauma, but meeting Mihashi, he felt he found his ideal pitcher. He has a short temper and often snaps at Mihashi, but he cares for and treasures Mihashi more than anyone.
