And in Asuka Mizunokoji's intro, while she's in the middle of some of her crazy training, the helmet of her oversized armor opens allowing Ataru to see there's a cute girl inside. He charges the field with one of Asuka's guards noting he did 100m in 7 seconds.
In Inaba's debut arc we're shown that the future is fixed, and that Ataru is fated to marry Shinobu and Lum is fated to marry Rei (both to Lum's horror). It's fate, they can't do anything to stop it, right? Wrong: in the greatest instance of Screw Destiny of Japanese animation, all the characters systematically destroyed the doors that kept destiny in place (with Ataru personally taking down the possible future where he had an harem because Lum was not in the harem), until future was not fixed anymore.
