Nanatsusaya/Kira Memory - Being found by Alexiel
Taken night 102
Sharable: horn with three mouthfuls of water

This page and the one after it.

This memory comes with a general impression of being locked in a cave for a really long fucking time. He knows he was there because he was considered too dangerous to wield, and none could endure his bloodlust. Eventually Alexiel waltzes in and tells him to acknowledge her as his master, and in exchange she would take him out of the cave and eventually maybe even tell him his name!

Nanatsusaya agrees because seriously, it beats being stuck in a cave. (ALSO, gay for Alexiel).

For Lucifer what this amounts to is that he knows Alexiel is a total bitch. She took him as her sword knowing he was Lucifer and hid that from him. He doesn't know how but he has NO DOUBT she knew him from before and this was fucking hilarious to her which is kind of hot. He also learns a bit of how his sword mechanics works: Alexiel was the only angel in the heavens with a bloodlust to match his, and thus the only one who could wield him. Others locked him away because they feared his power, and what he did to them. She, however, needed a powerful weapon for her battle against Heaven and went looking for the best. He technically had to do her bidding, because by accepting her as his master she could take the red crystal with his soul inside it and control him. But frankly that probably wasn't much of an issue. They both liked killing things so it worked out pretty well.

IT'S ACTUALLY A PRETTY FUNNY MEMORY FOR LUCIFER? At the time I think Nanatsusaya was a mix of frustrated and intrigued. But Lucifer can see how it is part of a puzzle and he suspects the large picture is that of a back-and-forth between the two of them for millennia. He still doesn't know HOW he got locked into a sword, shit she might be the one who did it. But he wouldn't hate her for that (though he might kill her for it...). If it was her own manipulative attempt to dominate him, she did rather well. If it wasn't, it's still a funny little piece of a game.

If he didn't know that he eventually gets free and is the one hauling her corpse around Heaven, and oh, her reincarnation was kind of dependently in love with his, oh and she eventually gets hit with the worst curse ever, he might be cranky about it. But since he knows he eventually gets the upper hand again it's just kind of lol.
