キラやば～っ☆ な「COTOHA DECO」作っちゃった！？よーしっ、さっそくQiitaへ投稿だーっ☆

わたし、《ことは ひかる》！
CSSとJavaScriptがだ～いすきなエンジニア。

ある日、Qiitaを眺めながらCSSを書いてたら、突然、 [謎のプラットフォーム](https://api.ce-cotoha.com/contents/index.html) を使った [キャンペーン](https://zine.qiita.com/event/collaboration-cotoha-api/?utm_source=qiita&utm_medium=article_banner)に出会ったのっ！

…これを使えば、「自然言語処理」 できるの！？キラやば～っ☆

Qiitaではフロントエンドエンジニアたちが、おしゃれな記事を書いて共有しているらしいのだけど…

あるとき、目的をはき違えた [センスのかけらもない記事](https://qiita.com/j5c8k6m8/items/dbc3a766b0c1daba7768) が、Qiitaに投稿されてしまったの！

「CSSの表現力をもっと伝えたい」そう強く思った瞬間、 [《構文解析》](https://api.ce-cotoha.com/contents/reference/apireference.html#parsing) を諦めて、 [《要約(β)》](https://api.ce-cotoha.com/contents/reference/apireference.html#summarization)、[《感情分析》](https://api.ce-cotoha.com/contents/reference/apireference.html#sentiment)、[《キーワード抽出》](https://api.ce-cotoha.com/contents/reference/apireference.html#keyword)、 [《固有表現抽出》](https://api.ce-cotoha.com/contents/reference/apireference.html#entity) の結果を使って、
文字列が長いほうから、タグ付けきの文字列に置換して、キラキラなCSSを書いていったら、
わたし、「COTOHA DECO」作っちゃった！？

よーしっ、さっそくQiitaへ投稿だーっ☆

わたし、《星奈ひかる》！
宇宙と星座がだ～いすきな中学2年生。

星空を観察しながらノートに星座を描いていたら
とつぜん謎の生物《フワ》がワープしてきたのっ！
それから、空からロケットが落ちてきて、
宇宙人の《ララ》と《プルンス》までやってきた！
…あなたたち、ホンモノの宇宙人！？キラやば～っ☆

地球から遠くとおく離れた《星空界》の
中心部にある聖域《スターパレス》では
《12星座のスタープリンセスたち》が
全宇宙の均衡を保っていたらしいのだけど…
あるとき何者かに襲われて、プリンセスたちは
《12本のプリンセススターカラーペン》になって
宇宙に散らばってしまったの！
このままじゃ星が消えて、地球も宇宙も、闇に飲み込まれちゃう…！

『星々の輝きが失われし時、
トゥインクルブックと共に現る戦士プリキュアが再びの輝きを取り戻す』
ララ達は宇宙に古くから伝わる伝説を頼りに
プリンセスが最後に生み出した希望・フワと一緒に
《伝説の戦士・プリキュア》を探していたんだって。

そこへ宇宙の支配を目論むノットレイダーがフワを狙って襲いかかってきて…
「フワを助けたい！」そう強く思った瞬間、《トゥインクルブック》から
《スターカラーペンダント》と《変身スターカラーペン》が現れて、
わたし、プリキュアに変身しちゃった！？

宇宙に散らばったプリンセススターカラーペンを集めて、
スタープリンセス復活の鍵となるフワを育てなきゃ！
よーしっ、地球を飛び出して宇宙へ出発だーっ☆
