Detective Opera Milky Holmes - Season 3 Episode 2 By Become, You Mean...

Alice and Kazumi decide to sneak into Holmes Academy for a chance to see Milky Holmes, where they end up getting inadvertently knocked out by them. As the two state their desire to be just like Milky Holmes, they simply respond by saying if they want it, they should just do it, whilst trying to keep up a classy image. Later that night, Alice and Kazumi encounter the thief from before, donning their new detective uniforms to fight against him. Whilst Kazumi's Arrow Toys prove to be ineffective, when combined with Alice's Barrier Toys, they combine into a powerful arrow that knocks the thief out. The girls leave the thief in the custody of the police, leaving behind a calling card naming themselves "Feathers".
