The ONA is basically episode 1 of the TV series. There are differences like: in the ONA, it just focuses on Makoto, Sekai and Katsura, and not giving the supporting characters (like Setsuna and Taisuke) any screen time at all (unlike episode 1 of the TV series). I also think the ONA made Katsura's breasts smaller. The ONA also shows Makoto asking Katsura out on a date, while the TV series doesn't. When Makoto gets aggressive towards Sekai, in the ONA, he shoves her to the ground (with Makoto on top of her), but in the TV series, he shoves her against the chain-link fence. |
