And that's when you used the Elixir.

...That's right.

I thought that it was the only choice left for me to get stronger.

The drugs had a huge effect.

So huge that it made the two months I spent training look like a waste of time.

Even though I knew it was illegal, I couldn't stop.

After I used the fifth one,

I challenged Theo to a fight.

I didn't stand a chance.

I couldn't even touch him.

That's when I knew.

That no matter how much effort I put in, and no matter how many drugs I use,

I'll never be able to close the gap between his true strength and mine.

But... But still, I wanted to let my sister fulfill her promise.

It's just like my sister said. I'm lacking in strength.
