Because there is always one hiding somewhere when my Izuna either land to recharge Boost (even at what seems to be the safest places) or get shotdown, then they'd pop out of nowhere, stunlock you till you are dead or ran away with most of your limbs and health missing. They love me. They are always there for me. They will never give me up. They will never let me down. They will never turn around and not hurt me. Hell, I can't even do SURPRISE-SLAYER-BIT-SUICIDE-DIVE-ON-YOUR-ARTS'-BEHINDS-MOTHERFUCKERS anymore with my Izuna, because THERE IS ALWAYS AT LEAST ONE OUKA. THERE. WAITING. FOR ME.
And they stunlock my Squealer whilst I tear shit up, hell, "high TGH? FUCK YOUR TGH I DON'T CARE I'LL STUNLOCK YOU LIKE THE LITTLE A.MAID YOU ARE." Machineguns and vulcans? Pfft, I can tank those. Trollberrls? I'll slice their head off whilst they have me bound. But Oukas? Oh look I'm stunlocked again guess I should just stop frankly smashing my keyboard foolishly hoping I can actually escape that crap.
