What were the filler episodes of Maison Ikkoku? While watching Maison Ikkoku, I noted the episodes in which the main story does not progressing. I found 23 episodes at total. I need someone who has read the manga to confirm them, or add/remove episodes from my list.

10 - Trip to sea
11 - Kentarou's first love
15 - Theatre club
16 - Kyoko injures her leg
20 - Shiner eye
21 - Kitten Kyoko
27 - The dog Soichiro is lost
28 - 3-legged race
29 - Festival ends in well
32 - Stupid egg
36 - Akemi's story
37 - Dress up
41 - Onsen
44 - Youtsuya's secret
46 - Ice skating
47 - Work at tavern
49 - Mitaka's dog fear
50 - Elder man moves in
51 - Ikkoku-han torn down?
67 - Grandma comes
68 - Baseball
69 - Kiss mark
70 - Grandma leaves
I did a similar list back in 2003 when I was watching the series for the second time through. I had read the manga before that, though I don't remember whether I took it into consideration when making the list. In general the anime follows the manga very accurately - if we ignore some blatant filler such as episode 32 (Yotsuya's egg; IIRC even its drawing style differs, so maybe the animators were using it for practice).

Your list corresponds to the B and C ratings in my list; B doesn't advance the main story but still e.g. develops the characters, whereas C is a pure filler episode. Except for a couple of episodes, our lists are similar.

It's interesting to notice that after episode 70 there are no filler episodes, and also on average the ratio of content to filler episodes is much better than in many other anime series. :)

A: Important part of the story
B: Could be skipped but is still worth watching
C: Totally irrevelant
