After Izumi called his Kingu (which means he can't call it because he doesn't know the name of it.) He takes a rest and will continue the training tomorrow morning. But, while he is sleeping, Someone called his name. The name of his Kingu. The voice is soft, deep, and with a badass tone. Just like his demon. But now is different. This voice is the Soul of his weapon.
Conversation: (in the dream.)
Voice of the Kingu:
"Rivai... Answer me... Are you the one... who is calling my name earlier?"
He said it with a badass voice, but the voice is hoarse, is as if you can't hear it.
Izumi is scratching his hair because he is sleeping and having a dream.
The voice of his Kingu ask him again:
"I'll ask you one more time... Are you the one who's calling me? My name, I mean..."
Same voice as the first one.
After that, Izumi answers the voice. In his dream of course...
Izumi:
"Hmmm... Who are... you? Yes... Yes, I am."
He asked it in his dream, with a low voice.
