The final episode starts with a Gunpla battle between various MS, including a MSM-03C Hygogg, a RX-77 Guncannon, a MS-14A Gelgoog, a YMS-15 Gyan, and a Z'Gok. Haru, Kenta, and Rina watch the battles and decide to enter the Gunpla Battle Championship. The Axis Hobby Shop manager then gives Haru some clear upgrade parts for the Beginning Gundam. Haru takes the parts and locks himself in his room while upgrading the Beginning Gundam. Rina tries to check in on Haru but his mother explains that he is in his room. Meanwhile, the Bandai employee confirms to Boris that he gave the parts to Axis Hobby Shop and is curious about how they'll do against the Forever Gundam. Boris says that he'll wait and see in the tournament and takes off with his wingmen Sam and Diana Lee. The next day the tournament starts with numerous MS entering the fight, including a Zaku II attached to a Zakrello and a MBF-P02 Astray Red Frame. Rina and Kenta are unable to get to Haru, and Boris wonders if he got scared. Entering as the Axis Team, Kenta enters the battle in his new MSN-04 Sazabi from the Reinforce Junior while Rina launches in her custom GPB-04B Beargguy. Both Rina's inexperience in combat and the normal Acguy being operable only on Earth lend to her being saved numerous times by Kenta (including kicking a 1/550 MA-08 Big Zam). Kenta then engages Koji's Hi-ν Gundam with their respective Funnels. Rina and Kenta are surrounded when Koji's Hi-ν is soundly defeated by Haru, who arrives in his new GPB-X80-30F Beginning 30 Gundam. After their reunion, Haru's friends are challenged to battle by Boris Schauer, Diane Lee and Sam, who are piloting a MS-18E Kämpfer and a RX-79BD-1 GM Blue Destiny Unit 1. Haru and Boris blast off each other's shields, while Rina holds off Diana Lee's Kämpfer with the Beargguy's Beam eyes. Kenta eventually defeats the Blue Destiny with his funnel supply depleted. Both Haru and Boris are giving everything they got to win, finishing off a team of mobile suits on the surface of A Baoa Qu. Boris says that for both of them, building Gunpla was fun, and Haru agrees as the two begin clashing beam sabers. The Beginning 30 Gundam, along with Boris's Forever Gundam, Kenta's Sazabi, and Rina's Beargguy appear in a collection of Gunpla a year later. The series ends with Haru now becoming a full fledged Gunpla Meiser along with his friends talking with two children looking at their custom Gunpla in Shizuoka.
