Word Meaning 根性

セッティングは整えておいたから、後はまーくんが根性見せなきゃダメだからね？

I've set the stage so now you just have to show some guts, OK?

大切だと思えば友達になれる！　互いを思えば、何倍でも強くなれる！　無限に根性が湧いてくる！　世界には嫌なことも、悲しいことも、 自分だけではどうにもならないこともたくさんある。 だけど、大好きな人がいれば、くじけるわけがない。あきらめるわけがない。 大好きな人がいるのだから、何度でも立ち上がる！　だから、勇者は絶対、負けないんだ！

If you care about someone, you'll become friends! If you care about each other, you'll become many times stronger! And your bravery will be unlimited! In this world are many unpleasant things, many sad things, and many that, which you can't handle by yourself. But while you have people you care about, you just can't fall! You just cannot surrender! While you have those people, about which you care, you will stand up again and again! That's why Hero is absolutely undefeatable!
