Episode 9 "The Fruit of all the Blood, Sweat, and Tears"
＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
Right before the Robotics Club completes the giant robot project GunPro-1, they go to Tanegashima's summer festival "Yoira~iki Matsuri" (lit. Let's Be Together Festival) to celebrate. Kaito goes to Frau’s house to invite her to the festival, and ends up waiting for her quietly alone. Akiho, who only has finishing the GunPro-1 on her mind, pours her heart out in a mail to Misaki. Then comes the day for the test run. Under the eyes of a crowd of excited onlookers, GunPro-1’s first test run begins.

The Robotics Club went through all sorts of ups and downs in making the GunPro-1, and they finally finished it. However, Aki, concerned about what her sister (Misaki), who is uncontactable, thinks of her work, was unable to let go and be immersed in the happiness and sense of accomplishment. Then we see lots of people on Tanegashima gathering to see the activation experiment of the GunPro-1. However, the GunPro-1 was a complete failure. The robot’s movements were sluggish, and the robot barely moved before coming to a complete stop with smoke pouring out of it. Akiho was utterly depressed by the failure of the experiment. This episode saw a gradual deceleration of the story’s development. Aki, who had been facing all sorts of difficulty with her brightness and fighting spirit, showed her fixation on her older sister, and other characters also began to reveal their true selves in this episode. Episode 9 described GunPro-1's failure, but left the viewers in suspense as to whether the Robotics Club would continue. Unveiling the world's unusual phenomena and mysteries one by one, what will happen to the Tanegashima High School Robotics Club? Look forward to episode 10 to find out!
