＞鍵山さんの御姿を拝見した記憶が、私の緩い頭ではあまりございません。
ヨハネさんのなかでは雛神様はどのようなお立ち回りでしょうか。

立ち位置ですか・・・。
そうですね「衣玖さんと仲良し」だと言えば、おおよそご理解いただけると思います。
「私が結婚できないのは！　きっと厄のせい！」と押しかけてきた衣玖さんとアレしてコレして、仲良くなって。という。

あ、そう言えば衣玖さんは名も知らぬメイド妖精さんと結ばれておられましたね。さすが厄神さま。

そんな雛さんのお話は紅楼夢合わせで描かせていただこうと思っておりますので、しばしお待ちを！

＞In my awkward brain, I don't have much memory about seeing Kagiyama san here.
So in Yohane's mind, where does the Hina-goddess usually hang around?

Where does she hang around...
Oh I get it! If I say "She is getting on well with Iku san", I think most of you will realize what I mean.
"Why can't I get married! It's all because of the misfortune!" And therefore she(Hina) will always be together with Iku san uninvitedly. There will be various kind of stories between them, and in the end they will become friends.

Ah, therefore, in the end, Iku san finally gets married to an unnamed maid fairy. This is certainly a gift from the goddess of misfortune.
(Although Hina is called a goddess of misfortune in Touhou by Zun, she is always trying to drain others' misfortune and thus make them more lucky. She is therefore in fact a goddess of fortune)

I think I will work out some doujinshi about such Hina's story on Kouroumu this year, please wait for a little while though.
