Ugh, I hate phased bosses
It's always the same getting careless after a supposed victory though - wouldn't hurt to stay vigilant just a little longer, instead of letting go of him right away...
It was a very Usato-style plan to knock out the opponent with a fire attack from Arc
while restraining him in person. Classic, "yeah burn me, I'll just heal".
And that arm strength to block an axe with just one arm
Thanks for the chapter!
