Bokura no War Game (translation)

sighing as I stare at the spreading sky memories were stuffed into the "time capsule"
let's leave without telling dad and mom everyone's energy is with me
let's go, the adventurer if the future let's search for the surrounding light
each day passes by quickly but I still remember every event up to yesturday
my secret is a gift to you leaving for the new world
events in dreams are true have courage and move foward
let's go, the adventurer of the future let's search for the surrounding light
many dreams will be waiting tomorrow we can probably become stronger than now
