Romance Blooming Academy Training with Yamamoto

As the title says. It's been a while since my last Success report, I guess. I trained a relief pitcher including Yamamoto. Getting Origin Rank 6 was quite difficult, and I finally managed to create a player I'm satisfied with. However, I couldn't get the 'Runners Locked' skill due to a lack of technical points. It's really tough without lower-tier skill cards. I didn't get it this time. Well, even if you get the skill cards now, their effect is somewhat reduced. Still, it's helpful to have them. I guess I need to be able to create players of this level every day in Power Challenge too.
