I checked, "ura-omote" (裏表) does indeed translate roughly to "two-faced".

And yes, this was a voice synthesizer.
Please, who can sing like this is either robotic or freaking monstrous.

Yes, that is a banana in the mv.
Yes, that is a pair of gender signs humping.
Yes, that is a bunch of sperm in there.

Strangely, the song is innocent enough.

Two-Faced Lovers
Wowaka ft. Hatsune Miku

The environment in my brain woke up from the dream where I was filled with fortune,
and got invaded by this strange thing called love, and since then...
One can hardly hold a capacity that can control the environment in their heart
that hopelessly got split into two, so that's why...
Inside the words that throws out typically ambiguous and innocent arguments
based on emotion,
"Life" longs for an eye that can somehow confirm where we presently stand.
Everyday which is filled with "why"-this then that then good bye baby.
Realism and escapism, my heart holds them both, and they lie closly together.
I ask to my flipped self, "Isn't there any star lying somewhere?"
I drag around my questions answered by myself, answered by others,
other's questions answered by me and aaaaaaaaah
I just touched due to instinct, but there's nothing I really want to say,
it hurts, so please touch me, breathing hard, we feel like we could rise up the sky―
This way and that, driven to the wall, there's no help―
just dive towards that side right away.

Ah, let's just get crazy about each other for now―
Diaphragm getting stretched―
Blown off by the powerful taste―
―face and back of candid selves.

Bind the other menacingly―
Paste it over their retina―
Ah, just go ahead and get crazy about each other!

I want you with me, with me now, I want you not, NOT I said!

The environment in my brain woke up from the dream where I was filled with distress,
and got invaded by this strange thing called love, and since then...
One can't just simply put a limiter to control the environment in their heart
that got split completely into two, so that's why...
Most are pregnant with egos that scatter disaster of ambiguous innocence,
and they somehow found the word that confirmed where they presently stand.
Everyday which is filled with "why"-this then that then good bye baby.
Realism and escapism, my heart holds them both, and they lie closly together.
I ask to my flipped self, "Isn't there any star lying somewhere?"
I drag around my questions answered by myself, answered by others,
other's questions answered by me and-- aaaaaaaaah
I just touched due to instinct,
but there's nothing I really want to say,
it hurts, so please touch me, breathing hard, we feel like we could rise up the sky―
This way and that, driven to the wall, there's no help―
just dive towards that side right away!

Hating you blindly―
Making plans for today with others on purpose―
Making you beg me―
Wait for the back side of candid self!

I allure you suggestively―
I sing out impulsively―
Ah, just go ahead and get crazy about each other!

Generally, no, love.

Ah, let's just get crazy about each other for now―
Diaphragm getting stretched―
Blown off by the powerful taste―
―face and back of candid selves.

Bind the other menacingly―
Paste it over their retina―
Ah, just go ahead and get crazy about each other!

Love(I), love(eye), love(sorrow), love, I'm saying it's nowhere!
