Dear, mom and dad.
I. Your son, Tenkai Hiro has died. But somehow, after I died it seems that I got brought to another world.
There, I fought and trained, I killed and survived in this horrid yet whimsical world for 5 years.
And along the way, I somehow found my new family and comrades and along with them, slayed the demon king.
Mom and Dad, I don't know if you would understand me, but I've grown pretty strong, strong enough to face the demon king! Unfortunately, it seems that this is a trial which I, the hero, need to face alone.
Mom and Dad...I want to see you again. Please wish me luck.
Ah, it seems that I need to enter now. Before I enter, I want to tell you even if you can't see this letter; Mom and Dad...I love you.
Love, Your son, Hiro. <<The Hero of Strength; The Hero of Sword>>
