Suki na Mono wa Suki Dakara Shouganai!
I Like What I Like, It Can't Be Helped!
(also known as 'Sukisho!' or 'Sukisyo!')

Sukisho! is a boy-love ('shounen-ai') Series about Sora Hashiba and Sunao Fujimori, two highschool students who share the same dorm room. They also have vastly different split personalities, Yoru and Ran respectively. The two boys have no control over when their bodies are taken over or what they do during that time, although Sunao at least seems to remember vaguely what he does. To make matters worse, Yoru and Ran are a couple, which leads to embarrassing situations for Sora and Sunao when they 'wake up'. Predictably but romantically Sora and Sunao also fall in love. The series is based on a (slightly more graphic) game version.

In Episode 4, "A Bandit Appears!", Sora is targeted one night when he's coming back from his 'club'-related duties by a man who refers to himself as 'Masked Bandit 416'. He introduces himself while standing in a tree. Sora refers to him as a "cosplay bandit", and the character he's emulating is obviously Tuxedo Mask from Sailor Moon.

Masked Bandit 416

He is dressed in a white tuxedo, a black and red cape, red tophat and black mask. He 'attacks' by throwing a red and white card at someone and then disappears, saying "We'll meet again", the exact same way + tone that Tuxedo Mask used to. The card says that he will take the person's most important thing, and he signs it 'Masked Bandit 416'.

Later in the Episode we find out he has an accomplice, Masked Bandit 773, an effeminate boy who wears a matching outfit but with rabbit ears instead of a tophat. It hardly needs to be pointed out the significance of rabbits to Sailor Moon...

Masked Bandit 773

They leap out the window with Sunao and a stuffed elephant (which is apparently Sora's most important thing), and 416 shouts "Farewell!" or "Saraba!", which was one of Tuxedo Mask's taglines.

Later, Masked Bandit 773 holds off Sora's friend Matsuri by tying him up with a whip + spinning him around. 773 summons the whip seemingly out of nowhere with a puff of pink smoke and a sound effect almost identical to the noise Luna-P made when it changed into something.
We later find out that 416 and 773 are friends of Sora, Sunao and Matsuri and were dressing up to try and bring out Yoru.
Most of the episode took place at night and full moons made frequent appearances. The similarities between this episode and aspects of Sailor Moon were obviously intentional. I think this plot also exists in the game, but I don't know how it plays out or if they still dress up as Tuxedo Mask.
Probably unrelated, but interesting nonetheless; the Voice Actor for 773, Nanami, is the same Voice Actor as Fish Eye.
