Okay. First, shout out to the raffle winner, @SadRen07 !

Second, this is tech done. I say that, with the understanding I COULD write more. But in my head, it's 'done'. If you want more, better like/share.

Hope you like it! Check out the Embers chapter!

At Izuku's whisper, Eri tugs his sleeve, flipping to a new page.

There's set of letters and numbers. Izuku has NO clue what they mean.

"It's Kacchan's code."

"Code? A code for what?"

Then, she smiles. "For your date tonight."

And Izuku's world is flipped upside down.

Eri grabs his hand, swaying their arms as she jumps and sings the lyrics. But she keeps looking at Izuku, making sure he's listening.

So when it ends, Kacchan tosses a final comment into the mic.

"And if you liked what you heard, Baby, you better come see me."

"See you?"

Izuku's cheeks go red as he stands there, unsure why his heart tries to break out from his chest.

But watching Kacchan openly sing these lyrics, that somehow feel like they're written for Izuku, makes it hard to breathe.

He shouldn't fall for this, or look into it, but...
sapphiretwilight.bsky.social
It's got a fun beat, the words a mixture of flirty and hopeful. It tells the tale of a 'unique' person who is too closed off to entertain love, but the singer wants to try.

Wants to risk getting shut down, like all the people he sings watch from the sidelines in quiet longing.
sapphiretwilight.bsky.social
And that gets the place buzzing, though Kacchan scans the front row, eyes stopping on Izuku and Eri before he nods. "Well, not ALL of you."

Speechless, Izuku can only watch as the man kicks the song into high gear, setting the place on fire.

With a song that's... meant for him?
sapphiretwilight.bsky.social
Stunned, Izuku slowly looks up, seeing Kacchan stepping in front of the mic stand. Hands start strumming a beat that the crowd goes crazy for.

Apparently, it's a favorite.

"Yeah, yeah, I hear all you extras." He scoffs into the mic, smirking. "But tonight, it's not for you."

"Oh, it's your song!"

"My what?" Izuku blinks, but Eri is already moving, pulling out the notebook and flipping to a page.

"Kacchan said to show you this on song eight." She turns the notebook, and sure enough, there's a note.

'Hey, Baby. Listen real close for me. -Kacchan'
sapphiretwilight.bsky.social
Izuku finds himself moving to the beat, dancing with Eri. And like she said, some of his songs are... sad. Like Kacchan has never felt like he could share himself with others.

From the front row, Izuku quietly sympathizes with the star.

Then, song eight comes, and Eri shouts.
sapphiretwilight.bsky.social
Eri doesn't mention anything about her talk with Kacchan at first, and Izuku thinks MAYBE he's being paranoid.

The show starts, and Kacchan is amazing. He sounds just like his recorded tracks.

He plays his own guitar, but has a background band that mixes rock and country.
sapphiretwilight.bsky.social
Before he can ask what that means, they're moved along.

Izuku looks over his shoulder as they're guided away, sees Kacchan still watching.

And the look holds a mischief that rings bells in Izuku's head. He can't shake it, even as they move into the venue and find their seats.
sapphiretwilight.bsky.social
"Okay!" Gone is the nervous girl from before, Eri happily hopping off her seat and rushing to Izuku. She doesn't give him back either item, seeming to hold them protectively to her chest. "Thank you, Kacchan!"

He waves, sending Izuku a look. "Should be thanking you, Squirt."
sapphiretwilight.bsky.social
Eri answers, and Kacchan says something else that makes her giggle and nods several times. Through this, she looks at Izuku several times, proving its about him.

But Kacchan then shut the notebook, handing it and the pick to Eri before ruffling her hair. "I'll see ya inside."
sapphiretwilight.bsky.social
"Hm." Kacchan takes the notebook and pick, grabbing his Sharpie and yanking off the cap with his teeth.

Izuku tries not to let his knees go weak. He watches Kacchan kneel next to the seat, writing on both items while he mumbles something to Eri too quietly for him to hear.
sapphiretwilight.bsky.social
"Dad?" Eri asks, looking at him. Izuku moves forward, pulling out the pick and his small notebook to hand to Kacchan.

"Um, just in case you-" their fingers brush, and Izuku sucks in a quick breath. Their eyes meet, a buzz sparking under his skin. "Need...more room to write."
sapphiretwilight.bsky.social
Once she rolls her eyes and mumbles 'two minutes' before sneaking away, Kacchan looks at Eri and shrugs. "Even adults gotta answer to someone, and Ears keeps me in check."

"That can't be her name," Eri says, and Kacchan hums.

"Guess we'll never know. Now, where's the pick?"
sapphiretwilight.bsky.social
Izuku tries not to swoon at how careful Kacchan is when lifting Eri up, placing her on the seat he used. A woman who might be his manager tries to call for Kacchan, probably to hurry them along.

But Kacchan gives her a fierce look that proves his gentle tones only for Eri.
sapphiretwilight.bsky.social
Eri looks star-struck by the kindness, nodding her head. "A pick. For my guitar."

"A little thing like you plays?" Kacchan whistles, dramatizing his surprise. "Wow. Think I picked up mine at ten, but you can't be that old."

"I'm eight."

"Baby faces must run in your blood, huh?"
sapphiretwilight.bsky.social
"Nah, they’re fine." Kacchan barely gives the people waiting a second look. "You've got something for me to sign, right?"

And its almost weird how the image feels right. Big, strong, famous Kacchan gently takes Eri's hand, slowly standing up and leading her like SHE'S the star.
sapphiretwilight.bsky.social
"Eri!" Izuku rushes out, unsure how to take Kacchan's tone. Eri's always been raised in a house that doesn't care about gender, but he knows not everyone is like that. And sure, Kacchan calls him cute, but it's probably more teasing. "We really should get going. The line behind-"
sapphiretwilight.bsky.social
THAT makes the singer scoff, turning his attention to Eri. "Your dad thinks I'm the cute one. You better make sure he gets his eyes checked."

Izuku chokes on his spit, but Eri only nods. "Auntie Chaco says he gets lots of attention, but he always turns the guys down."

"Really?"
sapphiretwilight.bsky.social
If Katsuki hears him, he doesn't comment. But his side-eye toward Izuku and his wider grin makes his heart skip. Was he... trying to embarrass Izuku?

Competition surges through him, his mouth moving without permission. "Then I think a cuter name would fit you. Like... Kacchan."
sapphiretwilight.bsky.social
From how Eri's eyes widen at the offer, she realizes how special this is. "I'm E-Eri."

"Pretty name, kid." Katsuki holds his hand out, Eri hesitantly taking it between hers to shake it. "Fits this family well."

Eri giggles at the compliment. Izuku goes bright red. "Wh-what?"
sapphiretwilight.bsky.social
"What's your name, Squirt?" When Eri struggles to answer, Dynamight cocks his head. "How about this? If you tell me your name, I'll let you and your dad call me Katsuki."

He doesn't know 'Katsuki' at all, but Eri says he has big boundaries. He NEVER lets fans use his name.
