- "... who could tell the son of Iwao Hazuki to stay out of trouble? I hate to say it but ... I feel like I'm letting your father down."
- ―Ine-san to Ryo Hazuki after eavesdropping on his conversation with Fuku-san.
Ine Hayata (Kanji: 早田稲, Rōmaji: Hayata Ine), more commonly known as Ine-san (稲さん), is the live-in housekeeper at the Hazuki Residence where she takes care of the basic running of the house. Ine-san is the mother-figure of Ryo Hazuki and has known him since he was three years old.
Ine-san was present on the day Lan Di came to the Hazuki Dojo and was attacked, or at least knocked down, by either Lan Di or the men in black suits. To cope with the death of Iwao Hazuki, she works hard and keeps herself busy to avoid depression.
Ine-san becomes very worried about Ryo and his quest for vengeance, but as time goes on she realizes this is something Ryo needs to do for himself and offers a little help when she can.
Ine-san's responsible for overseeing Ryo's curfew and also gives him an ¥500 allowance daily.
- Ine's zodiac sign is Leo and she has an A blood type.
