Background
A grade 2 sorcerer assigned under Nanami, which he treats as the honour it is. His shikigami are borrowed masks and he is candid that he is the least impressive person in most rooms he fights in.
Known techniques

Auspicious Beasts Summon
来訪瑞獣
Jujutsu Kaisen 0: The MovieEpisode 35
Ino's technique is unusual because it doesn't produce anything visible to opponents. There are no shikigami, no projectiles, no obvious tells, just a sorcerer who pulls a mask down and suddenly fights on a completely different level. The ability channels four mythological beasts through his own body, each granting a different combat enhancement. The catch: his face must stay hidden. The moment the mask comes off, everything shuts down. This condition makes the technique a fascinating risk-reward trade. Ino gains access to a versatile four-mode combat system, but a single well-timed grab at his face can leave him powerless. It rewards aggressive, front-foot fighting where the opponent never gets close enough to reach the mask.
Technique
Kaichi
獬豸
The first of Ino's four auspicious beasts. Kaichi provides mid-range offensive capability, cursed energy strikes that let Ino fight at a distance where he can control spacing before committing to close combat. It's his opening move in most fights, the first beast he calls because it lets him assess the situation from relative safety.
Technique
Reiki
霊亀
The second auspicious beast from Ino's arsenal. Reiki enhances close-range combat, coating Ino's extremities in cursed energy that increases striking power and provides a distinctive sliding movement across surfaces. The slide makes Ino's footwork unpredictable. He glides rather than steps, changing direction in ways that conventional fighters don't anticipate.
Technique
Ryu
竜
The third and apparently strongest of Ino's auspicious beasts. Its abilities were never revealed, Ino's mask was torn off before he could activate it, shutting down Auspicious Beasts Summon entirely. Based on the progression from Kaichi's ranged attacks to Reiki's close-range enhancement, Ryu likely provides an even more significant combat boost. It's one of the series' most tantalizing what-ifs: what would have happened if Ino had gotten Ryu activated?
