There's also an Animate in Shibuya which I like to visit too, though it is way smaller than the Ikebukuro branch... but to me, this is the second best Animate to look for Japanese BL manga, BL Drama CD or BL merchandises. Less crowded here too.
Pictures:
This is a random pic since I find the cover and characters attractive. Found out it's called "TYPE AID" by Ichigaya Mor. I wonder how's the story like...?
