The Alpha

While ignoring Echidna's scornful look, Icarus crouches near the monster's body

In doing so, Icarus once again sees the deplorable state of the monster's fur 

He then shakes his head and says in a sad tone

"It's a shame the monster's fur was completely destroyed. Otherwise, I'm sure it would make a nice armor

And given the stiffness that fur had showed, when that stupid dog was still alive

I bet if I use this fur to make an armor, it would have a much higher defense than what I'm currently wearing"

Despite this, that sadness doesn't last long and as he lets out a resigned sigh, Icarus concludes

"Well, now, it's already happened and there's nothing I can do to change it"

Echidna, who was floating beside him, nods and says

"Yes, you right, it's already happened. Also, don't be sad, you did the right thing!

Remember, between having new armor and not dying. The last option will always be the best choice!"
