Author's note: potential light spoilers for the Epilogue of Looking for Hope in this part and the next. The song above is what I think Kenta is feeling. 

Gone Too Soon (Where is the Good in Goodbye?)

This is a sick prank!

Ah, Death is a cruel mistress

I've lost a teacher

Never Forgotten

My pain has taught me

Your legacy must live on

I shall honor it

Anger

The universe's mean

It took away our anchor

And left us so cold

Denial/Bargaining

I'm sorry, sensei

If only I've seen the signs

You would still be here

Understanding

In his warm embrace

I let my restless mind race

Time to let you go
