Characters from AH1Edit
Heart and Saki are childhood friends who deeply care for one-another. Heart often goes to Saki whenever she is frightened or in need of help with school due to admiring her. She goes out of her way to make something very big and elaborate each Valentines Day just for Saki. But when Saki gets frustrated with her, she has a tendency to get childish and claim not to like her or start bawling out of fear Saki hates her or is upset.
Heart's other best friend. She portrays the same admiration and caring that she does for Saki - although not as much. While Saki may elicit a childish response for the way she handles Heart, this doesn't seem to be the same way when it came to Maori; most-likely due to her kind and motherly personality.
As Kamui acts like an older sempai towards her, Heart admires Kamui. She seems to know when Kamui may not be entirely truthful about her feelings, but she usually wont say anything about it either. She was very excited to teach Kamui how to bake.
Heart finds Konoha very adorable and will jump at her aid to lend her a hand or speak to her. She seems to like to touch, rub, or pet Konoha and affectionatelly addresses her as Kono-Kono.

Heart is very kind to Lieselotte; despite her plan to kidnap and harm her in the past. After Heart saved Lieselotte, she has no problems going out of her way trying to make her feel better. Such as the time she offered to give her umbrella to Lieselotte when they were out in the middle of a pouring rainstorm, then refused to use it for herself after Lieselotte did not accept it. She often calls her Liesy-Poo.
Heart doesn't agree with Kira's plans or ideals, or her own worship over herself. However, she will try to appease and tell her what she wants to hear; all the while trying to make a quick escape before Kira is able to respond or continue. Deep down she believes Kira really wants to have more friends and to be genuinely liked.
