Lock, Key, and a Maiden's Heart

(The author is usually busy, so updates may occasionally stop for a while.)

Monsters that bring destruction, embodiments of despair, the “Unlocked”: to face these natural enemies, a sleeping girl awakens.

But they don’t take anyone’s side. The girls possess immense power, making them ticking time bombs that could go off at any moment, even for humanity.

And that’s when it’s time for our Savior to step in!

“Huh... You mean me?” The boy pointed at himself in a daze, clearly not understanding a word of what had just been said.

This is a story that begins with you... The Savior protects the world and meets girls trapped in cages. Isn’t that the most wonderful kind of youthful boy-meets-girl romance?

“What have you been talking about this whole time...? And the way you describe it sounds an awful lot like "Operation XX"...”

Don’t sweat the details! So, are you ready to take that plunge?

Unlock the girls’ hearts and fall in love with them!
