AIR その町には夏が訪れていた。 人形を操るひとりの青年。 その周りには子供がふたりだけ。 観客の興味を引くには、青年の芸は退屈すぎた。 子供たちは興味を失い、その場を走り去った。 青年は旅のひと。 彼の道連れはふたつ。 手を触れずに歩き出す、古ぼけた人形。 「力」を持つ者に課せられた、はるか遠い約束。 そんな彼に、話しかけるひとりの少女。 人なつっこく、無邪気に笑う。 彼女との出会いをきっかけに、この土地での暮らしが始まる。 夏の情景に包まれ、穏やかに流れる日々。 陽射しの中で繰り返される、少女たちとの出会い。 夏はどこまでも続いてゆく。 青く広がる空の下で。 彼女が待つ、その大気の下で。 2000年9月8日にWindows用PCゲームとして発売したKeyの恋愛アドベンチャーゲーム『AIR』。 コンシューマ移植やTVアニメ、劇場アニメ、コミックなど様々なメディアミックスし、 発売より10年以上経過しているが、今だ多くのファンがいる。 ※本アプリにボイスは収録されておりません。 原画:樋上いたる シナリオ:麻枝 准、イシカワタカシ BGM:折戸伸治、戸越まごめ、麻枝 准 主題歌:『鳥の歌』(作詞:麻枝 准/作曲:折戸伸治/歌:Lia)
