On Keitaro's arrival at the Hinata apartments, Shinobu is already a resident in the manga, but in the anime she doesn't become a resident until episode 2. Motoko is present at the apartments in the Manga. In the anime she has gone away on a retreat and doesn't return until episode 3. These differences introduce characters one at a time, perhaps because this less confusing in an anime than introducing them all at once. Episodes in this category include episode 8, episode 9 and episode 11.
