【PC+KRKR+安卓直装】茂伸奇谈｜ものべの

いつまでも、このままで――

「ここがものべの !?　なーんにも無いねぇ」

高知の山深い寒村・茂伸（ものべの）村へと六年ぶりに帰省した主人公・沢井透と、ふるさとのことをすっかり忘れてしまったらしい妹・夏葉。

都会はおろか、他の人里からさえ隔絶された古びた空気の中、家守妖怪 “あかしゃぐま”の すみ、幼なじみの ありす、傘妖の 飛車角――

懐かしい面々との再会は、錆び付いていた記憶の時計を動かし始める。

大掃除、山遊び、水普請、畑仕事、牛鬼の来訪……

少しも変わらぬ茂伸の暮らしを重ねるうちに、やがて村に伝わる土着信仰 “ひめみや流” の夏祭りの夜が訪れる。

夜行市に賑わう境内に響く触太鼓は、祭りのクライマックス “面舞い” の始まりを告げるもの。

ちぐらとヒトカタとに守られた舞台に浮かび上がるは、七面頬（ナナツラオ）なる大妖と人間たちとが織りなす歴史。

その舞の最中、夏葉は突然倒れてしまう。

「おにいちゃん……夏葉……体がヘンだよう」

一晩にして十センチ以上伸びた身長、体型の変化、下腹部からの初めての出血。

夏葉の身体を襲ったものは、まぎれもない異常成長だった。

（このまま、異常成長が続いてしまえば……夏葉の命は！）

果たして原因は病か祟りか――

焦燥の中、すみとありすとの力を借りて、透は夏葉を救うための手掛かりを探し始める。

After six years, Tooru and his little sister, Natsuha, returned to the remote village of Monobeno, deep in the mountains of Kochi prefecture. They reunited with the Akashaguma (child-like Yamori Youkai) Sumi, the Kasayou Hishakaku, and his childhood friend and self-proclaimed fiancée, Alice. They played in the mountains, visited the shrine, and were visited by the Ushi Oni Tooko, just like in the past.

Just as they were getting used to living in Monobeno, it was time for the Shichi Seisai summer festival, dedicated to the local deity Himemiya-sama. The festival was lively, concluding with the masked dance. While watching the dance, Natsuha suddenly started shaking, complaining that her body felt cold. Tooru quickly took her to the doctor, but nothing seemed wrong with her. They went to play in the nearby stream the next day. Hearing the waterfall caused Natsuha to panic and run off in fear, but they couldn’t find a reason for her peculiar actions. That night, she appeared in front of them as an adult and bled in her nether regions for the first time. Unable to figure out what caused these inexplicable changes, they could only calm her down and watch over her. When they woke up the following day, they were shocked to see Natsuha was back to her normal size, but she didn't remember anything about the day before.

They decided to head back to the city for a proper examination. Unfortunately, a major landslide blocked the only access to the outside world. Natsuha wished to leave badly, saying something scary was coming for her. What was causing Natsuha’s changes? Was it a disease or a curse? Tooru was determined to find the cause and a way to save his little sister.
