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、時間がなかった
however there was no time
しかし、今はムリだ
however it's impossible right now
しかし、チャンスはまだある
however there's still a chance
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.
