I managed to secure a reservation for the Lindworm around 6 AM, and while I was still piping hot after my night shift, I went around to some secondhand shops and found a Gato's Gelgoog for around 2,000 yen (though it was missing weapons and effect parts), so I grabbed it.
I don't think I'll be able to reserve the Premium Bandai version, so I've given up on that, but I'd also like a Gato's Zaku.
However, I've never seen a Gato's Gelgoog before, so I don't know which one it is. Please let me know if the kit labeling is wrong. 🙏

I tend to buy hard-to-find models if I find a cheap, pre-assembled one. | けろごん's Gunpla works
