Waiting for Ikaruga

Ikaruga is mecha created by Eru after finishing some prototype. But event with the fast paced anime adaptation, this Silhouette Knight still doesn’t appear yet in main story.

This mecha is breakthrough in this universe. Because unlike any Silhouette Knight, it can fly. It can be done because this mecha using two Ether Reactor, improved with Eru ingenuity.  I really want to know their reaction when huge ass mecha could fly through the sky. But I heard the downside. The control is so difficult so only Eru capable piloting it.
