It looks like Riko and Shirokane meet again! It looks like they'll be classmates again as Riko goes to the hunting club, and Shirokane goes to the esports club. Both of them don't know they're both pursuing Hitonari's passions! And hey, they now are both seeing Hitonari's skills in action!
I feel sad for Okubo. Being passionate for gaming is one thing, but if it ruins your relationships and academics, you need to sit back and reassess it. Because it shows that you can't handle not playing it anymore. Takuma, you'd better learn from his mistakes, while you still can!
