Megahouse‘s official title for this 1/8 PVC figure is エクセレントモデルCORE クイーンズブレイド From Animation 戦闘教官アレイン / Excellent Model CORE Queen’s Blade – From Animation Combat Instructor Allean.
It is not explicitly stated whether this figure can be disrobed, but it seems likely cast-offability will be present in the final version, given that this is the same figure line as the earlier Reina Armor Failure and Megas ero-figures.
The sculpt of her clothing is particularly well done, such that it would (almost) be a shame to disrobe her more thoroughly if it turns out to be possible.
It is interesting to contrast her to her Griffon figure version, which was announced at around the same time as the Megahouse version, but has already become mostly sold-out online:
The more vivid color on the Griffon figure pops out more at the eyes, but its pose seems somewhat less interesting than Megahouse’s offering. The mouth on the Griffon Allean also seems preferable to the Megahouse figure’s somewhat odd snarl.
Admirers of Allean would probably be best served by getting both, since they both appear promising.
The Excellent Model Core Allean figure is still available online, although likely not for much longer as other shops already appear to be running out of pre-orders.
