Meeting Ben & IchigoEdit
Hiyori was introduced to Ichigo Kurosaki and Ben Tennyson when the pair came to the Vizard Warehouse to seek help in dealing with Ichigo's inner Hollow. Ichigo's brazen attitude annoyed Hiyori, and she attacked him, forcing him back, while demanding that he show everyone his Hollow. Before he could, Ben transformed into Articguana and briefly incapacitated Hiyori by freezing her, much to her fury. She broke free and attacked the alien, but was stopped by Ichigo. She mocks the pair, prompting Ben to transform into AmpFibian and electrocuted her. Now even more enraged, Hiyori prepares to renew her assault, but is stopped by Shinji Hirako and angrily introduces herself to the pair.
Training with Ben & IchigoEdit
Ichigo was forced to train with an exercise machine which Hiyori called the "Super Hiyori Walker", but everyone else mocked her for it. During this time, Ben played a joke on Hiyori by shoving a peeled banana in her mouth and calling her a monkey (due to the first part of her last name, "Saru", meaning "monkey"), much to Shinji's delight. Enraged, Hiyori spits out the banana and threatens violence against Ben, but her poorly worded threat allows Lisa Yadomaru to jokingly (yet emotionlessly) accuse the pair of engaging in oral sex, much to their disgust.
Later, Hiyori and the others fought a Hollowfied Ichigo so that the Substitute Shinigami could defeat his inner Hollow inside his mind. He notably took longer than she did in order to overpower his Hollow, and Hiyori said that they would likely have to kill Ichigo if the fight continued for much longer. Fortunately, Ben used Swampfire to stall the berserk Hollow long enough for Ichigo to overcome his inner Hollow and regain control of himself.
Fake Karakura TownEdit
Hiyori's grievous injuries are treated by Orihime. She does not bid goodbye to Ben, possibly due to needing to recover from her injuries or it could have been out of pride.
