＞正直、メイド妖精と衣玖さんのカップリングはきついです…天子さんの位置があまりにも宙づりなのが、そう思う要因なのでしょうが。

見くびらないでいただきたい。
既にして、私の中には「ここてん」という答えがございます。

私はオールハッピー主義者。誰一人欠けさせはしませんよ。

紅魔館でメイド妖精さんに食って掛かる

お嬢様にフルボッコにされて、逃げ帰る

トボトボ歩いてるところを、通りすがりの（最近貧乳に目覚めた）白蓮さんに声をかけられる

ひとまず、妙蓮寺へ拉致兼保護

表情を無くした天子さんに、表情を知らないこころさんが興味を持つ

ラブラブイチャイチャネチョネチョポンポン

とりあえず、こんな感じで天子さんのハッピーエンドルートは想定してございます。

むしろ私の中で宙吊りの心配は
「叩いてくれれば誰でもいい」深刻おひとりさまドM・雷鼓さん。
「最近太子様が構ってくれない」ふられた自覚が無い・布都さん。
「穣子穣子穣子穣子・・・」妹さん以外に興味もてない・静葉さん。

このあたりでしょうか。

To be honest, I think that the Maid Fairy and Iku pairing is rather cruel... Tenshi is just left hanging in the air. That is probably why.

Please do not underestimate me.
For I already have the solution, and that is "KokoTen".

I am the Advocate of Happiness for All. No one shall be left alone.

She went to Scarlet Devil Mansion and berate the Maid Fairy.

She got beaten up by the mistress, and ran away home.

As she was trudging home, Miss Byakuren(who just recently got interested in flat chests) who were passing by, called out to her.
↓
For the time being, she was abducted to the Myouren Temple for care.
↓
Miss Kokoro, who doesn't know facial expressions, took an interest in Tenshi ,who has lost hers.

Lovely Sexing Fun Time

Anyway, that's how Tenshi's Happy End route that I envisioned will be.

Rather, what's left hanging within me are:
Miss Raiko, a serious, loner, and extreme masochist who is "fine with anyone who'll beat her up".
Miss Futo, who isn't aware she's dumped even though "the Crown Prince doesn't bother her much recently".
Miss Shizuha, who is interested with nothing but her little sister "Minoriko Minoriko Minoriko..."

Pretty much those.
