Yuzuha Shiba/Relationships

Hakkai Shiba
Hakkai is Yuzuha's younger brother. He was only a year younger than Yuzuha but that didn't stop her from teasing or bossing him around. She calls him a "late bloomer" in the sense that he gets nervous around girls, except her. Despite all this, she really respects him.

Yuzuha has shown her loyalty and love for Hakkai on many occasions. In Chapter 78, we discover that she has a picture of him as her phone background. She also says that Hakkai could easily outrank Takemichi if he wanted to.

When we first see Taiju, he attacks Takemichi for being on Black Dragons territory. Hakkai attempts to deter him, thereby Taiju corners and threatens him as his captain. Yuzuha openly stands up to Taiju in front of the Black Dragons.

During the final showdown in the church, we learn that the entire time Hakkai was not the one taking the hits for Yuzuha. In fact, it was reversed; Yuzuha would admit to Hakkai's mistakes. She took the punishment for everything he did from Taiju. This truly solidifies her honest devotion to Hakkai.
