There is no way that I am a Gundam expert, and neither is my Chinese language skills all that well, so I’m relying on the comments posted in the video’s page to say that this is a “family” of Gundams: Exia, RX-78, and Z-Plus! Please do correct me if I’m wrong, and feel free to comment on their proper names so I can edit this!
…and am I right to say this was actually a wedding? Oh wow, talk about a unique approach! Thank you so much to Tania for sharing this video with us!
