Well...then Zuelni needs another city just for mass-producing heaven blades
.
Not to mention that in contrast with Suzaku and Kallen from CG. Layfon's power not just cause of genes but dead-serious training too(well...for someone to be HB reciever at the age of 10 it means he's a military arts prodigy)
Spoiler for Light Novels:
Now that Layfon fights with Savbaris maybe it means that at last we've got a strong antagonist for Layfon?
...I hope a bit not cause Savaris our most popular HB after Layfon, but a bit yes cause we've got a strong opponent for Layfon at last.
