Everyone forgetting that Ippo's not a southpaw? Sure he might have some insight about them now but it's not like he'll be able to properly emulate one without a ton of practice.
He's definitely gonna stroll over to the swamp and purify that shit right? Haven't seen him use his specialty Toxin Decomposition EX since like, the beginning of the series.
I wonder why it's only the Heroes' Sacred Weapons that drain their life force. Is it just the nature of them being that much stronger? Maybe their bodies can't handle the strain of the buffs?
