Aito smiled at Yumi's snicker, amused she found Viral's "ass" comment to be funny. His son did raise a fair point though, he was asking about something that really had never been addressed until now. Glancing back at Viral briefly the doctor let out a sigh, not seeing any point in trying to lie or twist the reality of things. "In part... Yes, you were made to combat these creatures," he admitted, looking out the front of the vehicle with half-lidded eyes, seeming to be in thought about something, "I'll explain everything to you when we finish today, I promise. There's a lot you and the others deserve to know, and I should have told you a long time before now." Ideally he'd prefer to do it with everyone around, yet telling Viral first seemed fair, it was his purpose after all.

Stopping the vehicle alongside the road Aito climbed out with the testing kit in hand, waiting for the others to join him. This wasn't particularly his idea of an enthralling afternoon, a fact which he made well known. Almost jokingly he offered it over to the others and got an unexpected offer in return, a very begrudging offer at that. Blinking a few times the doctor let out a chuckle, shaking his head and waving a hand dismissively. "I was joking Viral, it's really no bother. Besides if these are the same creatures then my Ki is useless anyways, you're more suited. I'd imagine they will try to stop the purification as it would eradicate them from the lake, so there's a chance the battle could be taking place on land." 

"What do you mean I need the practice, huh? I can fight just fine!" Yumi said haughtily, placing her hands on her hips and frowning at Viral, "I won't even fly if it makes you feel better, I don't need to. I fought just fine before I ever knew how to." Letting out a 'hmph' at the end she turned and started walking down the path towards the dam, determined now to fight and beat this monster herself. She was tired of everyone thinking she wasn't a strong fighter or capable, she didn't need practice. Practice was for someone just learning, she'd trained all of her life! So maybe she wasn't a Saiyan or a true Beastman, but she was just as strong as any of them, maybe even stronger, and better trained. She'd prove it today too.

Aito watched Yumi storm off ahead before letting out another sigh, rubbing at his head exasperatedly. "Oh dear... Seems someone is a little agitated today," he mused, smiling as he looked at Viral, "Seems like you've both got something to prove today, so let's give it our best shot, hm?" Slapping his son on the back for encouragement he started down the path as well, waving Viral along as he went. There very well could be nothing here to fight too, though the samples suggested otherwise. Aito in part hoped some of the creatures were here on Uuonoe, saved them from having to travel later to find some.
