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.”
