(The title, blurb, and protagonist's name may change, but the core gag of "pulling Lego Batman from a gacha system" will stay the same.)
(Finally able to show off this gorgeous coming-soon cover! So happy!)
Ailuo accidentally binds himself to a game System. The System tells him that, as a welcome gift for new players, he can draw three companion cards for free.
Ailuo is full of confidence and draws all three at once:
First card: Lego Batman.
Ailuo: Not bad.
Second card: Lego Robin.
Ailuo: Um... that'll do.
Third card: Lego Joker.
Ailuo: ...How much money did Lego pay your game company, huh?!
System: Congratulations, dear! Now please draw an enemy card!
It's probably a Lego villain too. No need to panic. Ailuo flips it over without a care.
A flash of golden light. The card turns over. Four big characters appear on it: The Batman Who Laughs.
Ailuo: ...I'm done. Delete my account.
The heir to Gotham's fallen Carlin family has returned.
Every Gothamite knows that the younger son of the Carlin family became an information broker. He's desperately short on cash and will do anything for money.
Lego Batman: You're short on cash? I can give you some. I'm a billionaire.
Ailuo: It's not money I'm short on. It's luck.
The Batfamily discovers that Ailuo wears many hats and has countless secret identities.
Robin Dick pats him on the shoulder and says gratefully: You've worked so hard to protect Gotham.
Ailuo: I'm not having a hard time. I'm just unlucky.
After going through countless trials and tribulations, Ailuo finally manages to drive away all the villains from other worlds that he drew.
System: Dear Host, due to a change in the game company's management, we have decided to erase all previous settings. The universe is about to reboot. Please prepare yourself.
Ailuo: …
GIVE ME BACK MY MONEY!!!!!!
Theme: Bravely fight back against a cruel fate.
