If you liked the NagisaXTomoya storyline in Clannad, then I'm sure you'll like Kimi ni Todoke. Unlike many series, while Kimi ni Todoke is a romance, the two leads' relationship progresses slowly, making it an absolutely adorable romance for those who love characters pining after each other.
Also centered around ballet, but this time with a magical-girl fantasy type storyline. Note: the anime is much better than the manga.
Gundam Seed is what you might call Code Geass' fraternal older twin. Like "Code Geass," it focuses on two childhood friends, Kira and Athrun, who end up on opposite sides of the battle. Lelouch fans/fangirls will be enthralled with Athrun Zala, and Suzaku fangirls will like Kira. However, this series is from Kira's point of view, so if you liked Suzaku's way of seeing war, then you'll agree with Kira. Strong female leads are a huge plus in this series, with Lacus as a more powerful Euphie, and Cagalli as a less fanserviced Kallen. Biggest Differences: space battles, both main characters pilot mecha, SEED spends more time on battles, Kira also has an evil girlfriend.
Both use "school girl in a strange land" plot, but differences between them are (that in my opinion makes it better) that Kanata Kara ends, not everyone loves her, and the characters are much more well developed. As for InuYasha the character, you'll love Izark!
These two series have similar protagonist: Both Light and Lelouch are extremely gifted students, and both receive a mysterious power from a benefactor who always stays nearby. However, Code Geass's Lelouch's problem is that in the year 2017 the Holy Britainnian Empire invaded Japan, and Lelouch aims to remove them from power in order to create a better world for his younger sister, Nunnally. Great cast. In my mind, Code Geass= Death Note and Gundam put in a blender. A great series for fans of both!
