[JoJo's Bizarre Adventure] Did You Drop This DIO, or the Devil?

People live to stir things up.

I only bought a Stone Mask to mess with my buddy a little. It's official merch, after all. It's not the most popular cosplay on Zhihu, so how would I transmigrate? Haha... Buying merch doesn't make you transmigrate, right?

Buddy, help!!!

Buddy: Don't call me, I'm working overtime.

[System] Congratulations, player, you have successfully reincarnated. The "Phantom Blood" storyline has begun. Choose a character to become a brother to.

Protagonist: Adults can choose both, right? Okay, just kidding. Obviously Jonathan...

[System] Congratulations, your choice is confirmed. You now have two older brothers.

Protagonist: ... Aaaaaah, take Dio back! I want a refund!!!

Dio: Hmph. I'll give you a nine-second head start.

Protagonist: Thanks for asking. I'm switching to being a JoJo-only fan tonight! I'm getting into the JoJo bedroom today, no matter what!

As long as you can get home, transmigrating isn't a problem. There's no such thing as someone transmigrating back into our world, right? Surely I haven't jinxed myself this time!

Protagonist: Opens the front door with total confidence.

Dio: Hi!

Protagonist: Closes the door. JOJO, SAVE MY LIFE, AAAAAH!!!!

Johnny: Punches his roommate. Shut up, you're annoying.

Jonathan: Um, I think the JoJo Damon called for is me.

Johnny: He's my boyfriend.

Part 1: Stone Mask

Part 2: Blood Bubbles

Part 3: Kakyoin Plushie

Part 4: Kira's Signature Cat Tie

Part 5: The Boss's Wig (in progress)

Part 6: Weather Report Plush Hat

The original idea was to transmigrate while wearing cosplay props. After transmigrating, the protagonist has the face and abilities of the character corresponding to the prop merch, more or less as that character's doppelganger or half-body. Relationships include siblings and parent-child ties (?

The protagonist has black hair (it changes color when he meets Part 7 Diego). His initial Stand is [Scary Monsters]. In the neighboring world are the Araki Mansion bosses who transmigrated back and got thrown in jail. He's a Part 1 JoJo-only fan. Current-world Johnny is his love interest.

The Part 7 cast is split into two groups: the current world and the original SBR Part 7. The current world is the new world where everyone from Parts 1 to 6 has a happy ending, and some characters have memories of their past lives.

Theme: Unlucky people can never beat the lucky ones
