"My daughter's 'Du' is way too kind!"
Okay, okay! Isn't it about time to feel some danger!?
A thought process no one can predict
Okay, okay! That empty feeling again!
I can't handle this on my own
Oh no... lately the demon world is peaceful
But maybe... this kind of thing isn't so bad?
Smile smile smile, all together now
One, two, three (what's this?)
I'll share it with you (yeah, yeah)
Everyone together, smiling
Everyone together, everyone smiling (yes! yes!)
Everyone together, everyone smiling (yes! yes!)
Everyone together, everyone smiling
Hey, wait a sec!
This won't do
No no no no no
I'm about to get swept away
I'm busy, you know
World domination!
This isn't how it was supposed to go
No no no no no
I can't let myself get swept away
To-do after to-do
Big teary eyes
I might start smiling
Two! Smile!
[Full Version Continues]
Now then! Invasion! Unify the demon world!
Everything goes my way-I'm the Demon King
Du, my daughter, you're too kind
Du du, ah ah ah
"Demon King!"
Oh no... at this rate the demon world stays peaceful
Nothing gets done, again today
Smile smile smile, all together now
[thanks for visiting animethemesongs.com]
One-let's split it in half (what!? )
This makes us happy (really!? )
Everyone together, smiling
Everyone together, everyone smiling (that's why!)
Hey, wait a sec!
This won't do
No no no no no
Being too kind won't work
The instincts of demonkind are
Cruelty! brutality! mercilessness!
Where did they even go?
No no no no no
I've got to get it together
Tasks piling up
The future looks uncertain
Well... sometimes that's okay
Smile smile, smile smile smile
Smile smile, smile smile smile
Smiles really are contagious, huh
This won't do
No no no no no
I'm about to get swept away
I'm busy, you know
World domination!
This isn't how it was supposed to go
No no no no no
Being too kind won't work
The instincts of demonkind are

No no no no no

[Correct Info]

Ahriman, the Demon King, once led the demon races—the very embodiment of evil—and conquered the world through sheer violence and power.

But one day, for some inexplicable reason, the Demon King suddenly put a stop to all invasion efforts!

Why would the strongest Demon King in the Demon Realm abandon conquest…!?

The answer is simple: his daughter, Du, is just too kind!!

Though born a demon, Du’s kindness knows no bounds. It’s so overwhelming that it soothes even the most vicious demons, the most ferocious monsters, enslaved humans, and even angels—the demons’ sworn enemies—leaving them all warm and fuzzy.

With a daughter like that, the Demon King can’t help but worry—so much so that conquest becomes the least of his concerns.

Watching her lord struggle, his aide Jahy vows to turn Du into a proper demon and begins putting her through all sorts of trials. Little does Jahy know that each challenge will only cause Du’s kindness to spread even further…

And so, Du’s gentle heart begins to send small ripples through a world that is anything but kind——
