If you're talking about Iroha, she's a crane, not a swan. She's based on a Japanese folktale.I think Sieger is a long, long shot. I think you'd see weird swan girl first.
How does she play?
Is Wanfu in? I can't remember seeing him. Will check later. Then there's the question whether or not he's sword or pillar Wanfu.I'm actually surprised we havent had Genan show up, either. Is he the only original game character to not be in the new one?
