彼かれは 背後はいごに 殺気さっきを 感かんじた

He sensed a strange atmosphere behind him.

大坂の人は殺気が多く、富を尊ぶ。

The people of Osaka are short in temper and they place importance on wealth.

鎌倉公方足利家に伝わる宝刀で、殺気をもって抜き放てば刀身から水気が立ち上る。

This is a treasure sword which has been handed down in the Ashikaga family, Kamakura kubo (Governor-general of the Kanto region) and it gives off a mist when drawn with an intention to kill.

また、｢そこで、御神霊の意見を是非うかがって、その返答によっては近衛の殺害も厭わない」と述べ、かなり殺気だった雰囲気に包まれたと言われている。

They also said in a stormy atmosphere 'we would like to ask the spirit about God's will and depending on the answer, we are willing to kill Konoe.'

日露戦争の沙河会戦で、苦戦を経験し総司令部の雰囲気が殺気立ったとき、昼寝から起きて来た大山の「児玉源太郎さん、今日もどこかで戦（ゆっさ）がごわすか」の惚けた一言で、部屋の空気がたちまち明るくなり、皆が冷静さを取り戻したという逸話がある。

An anecdote is left that in the Battle of Saka during the Japanese-Russo War: an atmosphere of the General Headquarters became frantic after experiencing a hard battle, Oyama woke up from a nap, instantly brightened up the air in the room and recovered everyone's composure by jokingly saying that 'Mr. Gentaro KOJIMA, is there a battle anywhere today?'

ハイド氏は青白く背が低い男で、どこといって奇形というわけではないが、気味が悪い印象を与え、笑い方は不愉快で、弁護士に対しては、臆病さと大胆さが入り混じった殺気を感じるふるまいをした、そしてかすれて、ささやくような、途切れ途切れの声で話した。

Mr. Hyde was pale and dwarfish, he gave an impression of deformity without any nameable malformation, he had a displeasing smile, he had borne himself to the lawyer with a sort of murderous mixture of timidity and boldness, and he spoke with a husky, whispering and somewhat broken voice;

近づいてくる足音を聞きつけ, 彼の顔に一瞬さっと殺気が走った. A look of menace flashed across his face at the approaching footsteps.すると、いままでおだやかだった場が殺気立つようになり、みなの顔色も変ってきている。

So, the calm atmosphere that had filled the place instead becomes bloodthirsty, and everybody there becomes pale.
