Passing the time with you when you’re in a bad mood, There’s one thing that I’ve learned. You’re just pretending to be like that and desperately fighting.

Don’t ever change yourself like the ice does. Even if the summer sun’s rays are hot, don’t melt away. I’m sure that just ahead, there’s a beautiful glacier. That kind of heart with a shape – if they’d realize it, all people have them. You have one too!

Hungry and unable to keep on walking, There’s one thing that I’ve learned. I’m putting off the things I should do and just doing what I want. I’ll eat my food and get ready to fight!

I want to have this forever – as strong as steel, A stubborn spirit that won’t let anything through. I’m sure that even now, it’s in the middle of standing still and defending. Countless enemies are in my way Waiting for me Waiting for you, too
