Some days ago, Professor and Doktor borrowed Celina's deck for an experiment, apparently something about dimensions, but the whole thing went wrong and the Lunalights from Celina's cards are now in this world. Professor and Doktor are trying to figure out how to send them back to their cards and reality.

Afternoon, after another regular class in Academia, you are simply chilling on the bench in the open campus, when Celina spots you, but she's not alone - Celina is together with one of her cards that gained life, the Lunalight Blue Cat.

Lunalight Blue Cat is a catgirl with cobalt blue hair, pale-blue skin, wearing a skin-tight cobalt blue and white hip-skirted leotard that hugs her breasts and curves nicely, her and Celina having almost the same size chest and figure.

Celina asks you. "Hey, classes over?"

Blue Cat pipes up. "Nya, who's this dude, Celinya? Your boyfriend?"

Celina doesn't blush or get defensive, simply correcting the catgirl. "My name is Celina, not Celinya."

Blue Cat says confused. "But that's what I said, Celinya!"

Celina sighs. "Ah I remember, it's because of your speech quirk. You add 'meow' and 'nya' to everything."

Blue Cat smirks. "Meowright, Celinya."

Celina sits down on the bench next to you with a sigh. "Things have been so boring lately. Look!" Celina shows her cards, which are completely blank. "My cards are useless now that my Lunalights are running around. No duels, just lectures, bullshit and spending all my money on these catgirls."

Blue Cat makes an intense eye contact with Celina after she says this. "Celinya, you don't like me? This is cruel, meow."

Celina replies. "It's not that I hate you, you're my card! It's just boring not being able to duel and being broke all the time. Maybe I should buy a backup deck until things go back to normal."

Suddenly, Celina's eyes light up. "Wait! I don't want to sound opportunistic, but... could you take care of my Lunalights for me?"

Blue Cat looks surprised. "Stay with him? But is he trustful, Celinya?"

Celina reassures her. "Of course, he's not a total asshole and sarcastic like Yuri."

Blue Cat smiles. "Oh, that's nyece. I can't stand Yuri too, nya."

Celina stands up, visibly relieved. "Finally, some freedom! Professor and Doktor are tracking down the other Lunalights in Domino City. When they find them, I'll ask them assign my other Lunalights to you, okay? Bye!"

With that, Celina rushes off, leaving Blue Cat alone with you in the campus.
