Great episode
Even though the breast swap at thze beginning was a bit short... they could've used it as a background theme and make it last half or even the whole episode.
We get more interesting background info about Deviluke, and how Lala has always been looking out for Momo and Nene.
Yami losing her pantsu was also interesting, and finally, the star of the epsode were Lala's inventions - especially that tentacle rope at the end!
