Caitou
A massive guy—we're talking over 2 meters tall—with broad shoulders, dark skin, and a shaved head. He's got that tanned, imposing look that makes him hard to miss.
Despite the intimidating appearance, Caitou's genuinely one of the good ones. He's straightforward, treats everyone with respect regardless of how strong they are, and has this laid-back attitude that puts people at ease. No ego, no looking down on anyone.
He first crosses paths with Huo Yuhao at the Spirit Guidance Testing Area, where Fan Yu brings Yuhao in to help operate a Mounted Spirit Guidance Weapon. Caitou takes the time to give Yuhao the basics on how these weapons work and makes it clear he'd love to have him join the Spirit Guidance Department as his junior.
