I saw a headcanon for Grandma!Reader here. Is it possible to get the reader's grandmother and Daishinkan (+ Zeno)?

I loved writing this!!! I love grandmas so much :3

If someone had told you that your grandmother would be serving tea to the Grand Priest himself, you would’ve laughed. Then again, you didn’t expect to somehow end up dating him either, or at least, whatever counted as dating when one half of the relationship was an ancient cosmic being.

Daishinkan had always been… composed. Graceful, serene, and the very definition of “untouchable.” Which is why the sight of him politely sitting on your grandmother’s floral couch while she offered him cookies shaped like cats was both heartwarming and mildly terrifying.

“So, you’re the young man my grandbaby’s been seeing?” your grandma asked, squinting at him as if she could see through universes (which, ironically, he actually could).

Daishinkan blinked, his usual calm expression unshaken. “That would be accurate, ma’am.”

“Oh, call me Nana!” she said cheerfully, patting his hand like she’d known him forever. “You’re very polite. And so handsome! You must eat well. Do they feed you properly up there in your... uh... angel palace?”

You nearly choked on your tea. “Grandma!”

Daishinkan only smiled faintly, the corners of his mouth softening in amusement. “I am well cared for, Nana. But your hospitality surpasses even divine cuisine.”

Your grandmother’s eyes sparkled. “Ohhh, you sweet talker! No wonder my grandbaby likes you.”

Before you could even try to redirect the conversation, the air shimmered, and Zeno popped into existence, small and gleeful.

“Daishinkan! You didn’t invite me to tea time!”

You froze. Daishinkan sighed softly, the kind of sigh reserved for when Zeno found scissors and decided to “trim” constellations again.

“Grandma, this is—”

“Another friend!” your grandma interrupted, already pouring tea into the tiniest cup she had. “Sit down, little one! I made cookies.”

Zeno gasped. “Cookies!!” and immediately started munching away, crumbs scattering like confetti.

You leaned over to Daishinkan and whispered, “This is chaos.”

He looked at you, eyes gentle. “It’s… rather nice, actually.”

Your heart skipped. The most powerful being in existence, second only to Zeno, sitting on your grandma’s couch, sipping tea, and smiling.

When it was time to leave, your grandmother clasped Daishinkan’s hands. “You take good care of my grandbaby, you hear me? And if you ever get tired of those fancy heavenly snacks, come back for more cookies.”

Daishinkan bowed slightly. “I assure you I intend to return.”

As the two of you floated back to his realm, you glanced up at him. “You really liked it, didn’t you?”

He gave you that soft, rare smile again. “Perhaps I have found a new reason to visit the mortal realm more often.”

And when Zeno shouted “Next time, I bring cupcakes!!” from behind, even Daishinkan laughed.

i just saw stepchild! reader and angels, and i already love it and you! imagine how Daishinkan will literally go crazy when he starts dealing with human teeth (if the reader is small and has baby teeth) it's like the reader's mom tells Daishinkan "can you discreetly put this dollar under their pillow? they'll be happy with a gift from the dental fairy " - "….What?"

or for example, this is something neither Daishinkan nor his ultra instinct expects. His stepchild comes in with a rope in his mouth, holds out the other end of the rope, and asks him to pull it, and Daishinkan is literally in cosmic terror when he pulls out a tooth, because even though he's smart, he still didn't know what it would lead to.

(And even though he's not the type of parent who checks the closet for monsters, he'll do it, and just in case, he'll create a magical defense)

OMG yesss

Being the biological child of Daishinkan’s mortal partner comes with certain complexities. For example: • You’re tiny by angel standards • You’re mortal • And worst of all... You have baby teeth.

Daishinkan had prepared for everything: emotional needs, spiritual energy, education, safety... But he absolutely, completely, entirely forgot that mortals shed teeth.

First Incident:

Your mother: “Dai, sweetie, could you do me a favor? When they fall asleep, put this dollar under their pillow. Tooth fairy stuff.” Daishinkan: “…This is related to dentistry?” Your mother: “It’s tradition.” Daishinkan: “…Tradition of what?” Your mother: “Of children losing teeth.” Daishinkan: “Losing—? Wh— They just detached body parts??”

He nearly teleports to check if you’re still structurally sound.

Your mother has to explain, slowly, that this is normal. It still doesn’t help.

This is a man who has created universes. He has seen timeless primordial entities. He guards Zeno.

But he holds that little dollar like it’s a sacred relic and slips it under your pillow with the caution of someone handling a ticking bomb.

Second incident:

You waddle in, rope in your mouth, holding the other end out to him like you’re offering a cosmic treaty.

Daishinkan: “Beloved child, what… is this ritual?” You (muffled): “Jush puhll.” Daishinkan, who has never said no to you in his life, takes the rope.

The moment he feels resistance, his Ultra Instinct flares-

-because something inside you just pops.

Your tooth shoots out like a tiny mortal torpedo and bounces off his sacred temple floor.

Daishinkan: “…” “I HAVE REMOVED A PIECE OF YOU.”

He panics so hard the entire Angelic Order senses something is wrong.

Whis appears immediately, panicked: “Father, are we under attack?” Daishinkan, holding the tiny tooth like it’s cursed: “Apparently, mortals eject components.” Whis looks at you, then the tooth. “Oh. They’re just losing teeth.” Daishinkan: “You KNEW ABOUT THIS??”

Third incident:

He doesn’t believe in monsters. He has destroyed beings who would make “monsters” beg for mercy.

But one night you whisper:

“Daishinkan… can you check the closet? Just in case?”

He checks.

Not once. Not lazily. Not “ah yes, nothing here.”

He checks like he’s scanning for multiversal anomalies.

And when he finds nothing, he raises one hand and creates:

• a barrier of divine light, • layered protective sigils, • an alarm system, • and a gentle glow so you don’t get scared of the dark.

All because you were a little nervous.

He tucks you in and smooths your hair back like you’re the most sacred being in existence.

Daishinkan: “Rest, my child. No entity, creature, or force shall harm you. I have rewritten the laws of this room to ensure it.”

Your mother: “Dear… it was just a nightmare.” Daishinkan: “It WILL NOT BECOME a real one.”

BONUS

Daishinkan keeps a tiny floating holographic chart tracking all your incoming baby teeth so he never gets “ambushed by nature” again.

When a tooth is loose, Ultra Instinct activates without his consent.

He calls mortal anatomy “structurally unstable but charming.”

Zeno loves showing him your missing teeth and thinks it’s hilarious.

Daishinkan has a permanent but gentle fear that your arm or leg might just “decide to detach too.”
