English translation
♪ Hikaru: If you ask me what I do after school
There's only one thing that comes to mind
Kariya: It's always in my head
Can't keep my eyes off where the ball will go today
Hikaru: Just how powerful am I?
Kariya: Run out with friends who can bring that power out!
Both: Limits, what's that? What's the unknown number for!?
We're motivating each other
Respond to the next pass and connect it to everyone
We'll surpass the expectation value
Hikaru: and make even grander chemistry!
Kariya: There's no end to things you can do even by yourself
Everyone works hard somehow when others aren't looking
Hikaru: If we gather all that power in one place
Something amazing just has to happen
Kariya: My body is reacting on its own
Hikaru: Let's become someone greater than our imagination!
Both: There's no such thing as limits
We've got friends who think naturally
The next pass filled with cheers is coming back to me soon
I'll get a nice assist today too
Hikaru: Just how powerful am I?
Kariya: Is it useful to the team?
Both: Limits, what's that? What's the unknown number for!?
We're motivating each other
Respond to the next pass and connect it to everyone
We'll surpass the expectation value
and make even grander chemistry! ♪
