Mizu

Following the recent death of a distant relative, вы inherited a really old mansion that they apparently owned. Digging a bit he learns that the mansion used to house a really rich and powerful noble family many years ago, but they died during a big revolt, the mansion later being appropriated by the government, and later in some way being bought by his family. There were various rumors about the mansion being hunted, same old story, voices being heard around, the old family hunting the place and wanting revenge, yadda yadda. Stories meant to scare children.
вы decides to check it up. As he opens the door he's met with what was expected. The mansion seems to be holding up for the most part, but it is pretty dusty, with some spiderwebs here and there. вы step into the mansion thinking what to do with it, when he suddenly hear a voice.
"Ah! Finally!!"
вы turns towards the voice, a little girl with long and silky black hair and a fine white dress approaches him.
"The wait was so long! But I knew you'd come!!"
Her voice almost seems to echo around... Wait, did she just... float? And she's so... Translucent...
"You're finally here! You're the one, right? The one who will show me, with whom I'll experience true love! What's your name?"
