History Heartwarming / GundamBuildFightersTry

* Sekai having complete faith in his big sister was very heartwarming, showing that they both love and respect the other

** Extra heartwarming from a meta standpoint. Given the gunpla we've seen around him, Mamoru is obviously a huge [[Anime/MobileSuitGundamSeed Cosmic Era]] fan, and in that very scene has his new Destiny Impulse and a [=LaGOWE=] on the bench (his hat even has a stylized ZAFT logo on it). Tateo, given his Gyan obsession, is clearly a huge [[Anime/MobileSuitGundam Universal Century]] fan (his backpack has a Zeon uniform insignia on it), and there is no animosity whatsoever between the two.

** Also the final image of the girl's Gunpla, along with Reiji's Beginning Gundam and Aila's Command Gundam.]

** During the stinger of Episode 9, [[spoiler:Fumina personally visits Sekai, who is still sleeping off his injuries, to tell him thanks for bringing them to the national championships.]]

* In the final move Sekai [[spoiler:using the Lightning Gundam's jetpack, the core fighter of the Winning Gundam and Sekai entering Burning's SuperMode, states Team Try Fighters are all connected.]]

** So did Lady Kawaguchi to Fumina. [[spoiler:Granted she was a bit rougher than the Meijin, but she got her point across...]]

* After all of this time, all the hard work and sacrifice [[spoiler:not only did Team Try Fighters finally make it to the top, Wilfred obviously had a massive blast with the fight.]]

--> [[spoiler:I'll be waiting for you at the World Championships!]]

* Pretty much all of it. From Mamoru [[spoiler: losing his division, but gaining a rival (Gyanko's little brother, at that)]], to absolutely everyone jumping into the duel between Yuuma and Minato and having a blast. Hell, Ramba Ral even finally got that Dom(look out, Amuro!).

* The credits, TheStinger and the final scene. [[spoiler:The mysterious girl is revealed to be Reiji and Aila's daughter, and she happily greets her mother upon returning to Arian.]]
** Also the final image of the girl's gunpla, along with [[spoiler: Reiji's Beginning Gundam and Aila's Command Gundam.]]
*** Mind you, the last time we saw [[spoiler:the Command Gundam, it was on ''Earth.'' This means Aila (and/or possibly Reiji) had to have gone back to get it from China.]]
*** Possibly foreshadowed. Back during the finals, when China calls for the unseen Sei that they're starting, there's a quick cut to four teacups setup on their coffee table. While it could easily have been for Sei's visiting parents (China and Yuuma's were shown to still be in Japan), that may have been the first hint that [[spoiler: Reiji and Aila had indeed been able to return, and that's when Aila got the Command Gundam from China. And seeing as Reiji ''does'' show back up in ''Gundam Build Fighters: GM's Counterattack''...]]
* A subtle one compared to the rest of the OVA ; In the aftermath of the three great superweapons firing, when all hope seems lost, and the Build Fighters are at their weakest Sekai stands up above the sky of Sydney..and prevents the first, most fundamental, most devastating, senseless loss of life in Gundam history. It's entirely symbolic, but it's one of the most powerful moment in Gundam history that was changed by the willpower of the protagonists. And they deserve it.

* Fumina tackle hugging Sekai and Yuuma in episode 5 after their first win. You can clearly see how happy she is to finally make it out of the first round of the regional tournament after having failed so many times in the past, and is thankful for her friends who helped her achieve that.

It's entirely symbolic, but it's the most powerful moment in Gundam history change history. And then his team get onboard with him..
