The Story So Far:
You are Elly, an ex-shinigami who has broken ties with the Yamas, and now serve under Yuuka Kanzami, the flower master of four seasons, guarding the gate to the Dream World, which in turn keeps you safe from the retribution of the Yamas, as the land is beyond life and death.
Yuuka gave you some time off, and sent you to Gensokyo to do whatever you felt like, because you hadn't fought for a while. Eventually, you decided to start up an incident to get revenge on Reimu for bargeing into your house. You gathered several notable figures to aid you, such as the Scarlet Devil Mansion, Nue and Mamizou, Tenshi, and Eirin, and working together, you managed to outwhit and eventually defeat Reimu. You also found a strange tree youkai, who was later revealed by Yuuka to be the one which your scythe is made from.
However, Komachi found you almost right afterwards, and used her distance manipulation to take you to Higan, to face judgement by the Yamaxandu. Eiki gave you the chance to fight for your freedom, as the Celestials got to, but instead of fighting a reaper, your foe was her. After a long battle, with help from Yuuka, your scythe was imbued with some strange powers from Eiki's stand, and you managed to fufill the condition of injuring the Yama, before Yuuka went too far and outright defeated her.
A few days later, you were guarding the Dream Portal, which shifted to a different dimension than Yuuka's. Curious, you went to investigate, and entered a strange world. After talking to some strange orbs, you flew towards the moon in the sky, and have come across a strange, maid-like figure.
>Let's tip our hat a bit, gotta be polite. "Name's Elly, this here fine piece of work is Malus. I actually keep an eye on the portal from the other side. I guess you could call me a gatekeeper."
>Sigh. "The big problem though, is that there's only one portal, and I can't get in touch with Boss if the portal's connecting here instead of her world. And even though she's pretty strong, I still worry about her."
> "Ah, so you're here because of duty on the other side, eh?" Mugetsu says, with a small smile.
> She pauses for a few moments.
> "Truth is I hoped someone would investigate. I opened the portals as a cry for help. My sister is getting out of hand, and risks this whole dimension's stability if she continues."
