Maison Ikkoku, Volume 4 (2nd edition)

Now everyone seems to forget that "home is where the heart is"! First Kyoko's dog Mr. Soichiro (named after her late husband) gets hopelessly lost. Then a misunderstanding causes Yusaku to move out of Maison Ikkoku in a huff. Unfortunately, the tiny apartment he moves into is still occupied - by a beautiful masseuse and her apelike yakuza husband.
