ここ数日、妙な事件が続いている。
ひとつは何の理由も無く突然他者に襲い掛かり負傷させ、酷い時は殺害してしまうという事案だ。
これだけなら良くある基地外の犯行に思えなくも無いが、奇妙なのは被疑者全員が犯行直前まで”普通”だった事だ。
前科も無ければ精神病歴も無い人間が、仕事の途中、買い物の途中、会話の途中に、突然発狂し、暴れだしたという。
新手の麻薬でもｷﾒていたのか、それともこの暑さで本当に狂ったのか。
いつもと違って何かがおかしい。
けどその”何か”が分からない。

For many days, the strange incidents continued.
In one, someone suddenly began attacking others with no particular motive, while at worst murders were taking place.
This might have been ascribed to insane criminals, but the strange thing was all these people had been completely 'normal' before committing their crimes. They had no records of criminal or psychological abnormality, but simply went mad and lashed out while working, shopping or having a conversation.
Were they taking a new narcotic, or did the heat simply drive them mad?
Something was unusual, wrong. But what could that be?
