Today I completed my second model from the Muv-Luv franchise, this one being the Takemikazuchi, which many fans will agree is one of the best of the TSF lineup.
Mild spoilers in this paragraph.
Some brief background here, this is based on the Type-00R Takemikaduchi, which is reserved for use by the Shogun and the the houses under the Shogun. Purple (like this model) denotes use by the Shogun themselves. This TSF model is (in-universe) among the strongest, most difficult, and most costly TSFs in the world. It's reserved for exclusive use by the royalty of Japan.
This model's build time clocked in at about 2 hours and 30 minutes, mostly due to a piece that just would not stay where it should have (I eventually managed to lock it in without glue).
