- Heartwarming Moments:
Nanako: Danke. Grazie. Merci. Xie Xie. Arigatou.
- The ending of Episode 8 had a lot of viewers feeling po-warm. Happy birthday, Nanako!
- Episode 12 combines this and Tear Jerker when everyone has to go back to their separate universes, but they're grateful for all of the fun times that they shared.
- Ho Yay: Mostly between Subaru and Aoi. Doesn't get helped even by the stereotype Subaru vehicles were labelled as "lesbian cars".
- They Wasted a Perfectly Good Plot: People sometimes wonder if this will actually sell Subaru cars or even the Initial D manga to the Otaku. Others think that this is a good series that should pick up full production.
- Viewer Gender Confusion: Minato. It's easy to mistake him for a girl because of his voice.
YMMV / Houkago no Pleiades
