Kazuha Hitachiin (常陸院 和葉 Hitachiin Kazuha) is the maternal grandmother of Hikaru Hitachiin and Kaoru Hitachiin who is in her 50's and a talented Ikebana (flower arrangement) artisan with an Ikebana company is in its seventh generation.
Story
Kazuha owns and motorbike and likes doing adventurous things. She is known to go travelling without warning, and even her family can only keep up with her whereabouts by word-of-mouth or spotting her in magazines. In contrast to her outgoing nature, her husband is meek and quiet, but accompanies her on all of her travels.
Kazuha loves to tease her grandsons, but she secretly holds them very dear, and it is seen that she actually carries one of the drawings that she insulted when they were only five. Her unusual hairstyle was created by the twins when they were very young during an attempt to pull a prank on her; ergo, anyone who insults her hair is immediately on her bad side (like Tamaki Suoh).
The other hosts meet her when she helps them dress for a club event, but shes leaves as quickly as she arrives. Haruhi Fujioka never meets the woman, but by the twins's anecdotes, she thinks Kazuha's personality is exactly like theirs, though they deny it and claim that she's a terrible adult.
