The Ravon that Kira had summoned had been following Aaron all this time. It was true that Aaron was quite a fast runner, but by no means was he faster than the summoned Ravon's flight.
Of course, Ravon prevented itself from being detected by Aaron. Also, the Ravon was quite careful in following because it couldn't possibly forget about informing Kira!
Well, the Ravon maintained an equal distance between Kir and Aaron. It didn't miss Aaron because it had exceptional eyesight which was called 'Eyesight of the Dark Ravon'.
'Just how far has Aaron gone to?'
Kira was worried even now, in fact, his worries didn't cease. But there was something else that he was worried about at the same time.
'I hope nothing wrong would happen while I'm not around...'
'I guess Siara would take care of them...'
