Shigure's the dog of the Chinese Zodiac—he transforms whenever someone of the opposite gender hugs him, or if he's under enough physical or emotional stress. As one of the Sohma family's oldest members, he's pretty much the opposite of what you'd expect from someone in his position. He's laid-back, goofball energy, definitely a bit of a pervert, and writes for a living—both romance novels and academic work, which is kind of a funny combo.
But here's the thing: beneath all that casual charm, Shigure's got real depth. He drops the act and becomes genuinely thoughtful and wise when it matters, offering solid advice to Tooru, Kyou, Yuki, and others. Fans often note how he can switch into an actual adult mode when the situation calls for it, revealing a surprisingly mature side that balances out his usual goofy persona.
