However
conjunction
She cashes (しかし) in on everything. However, this time you're going to stop her. No more cashing in.
しかし is used at the beginning of a sentence, just like "however." It's pretty formal, and you'll see it much more in written Japanese than spoken Japanese.
しかし、チャンスはまだある
however there's still a chance
しかし、今はムリだ
however it's impossible right now
しかし、時間がなかった
however there was no time
しかし、それはウソだった。
However, that was a lie.
しかし、その日は雨だった。
However, it was raining that day.
しかし、女王に見つかってしまった。
However, she was found by the queen.
