Fubuki/Relationships

Saitama
She strikes up an odd friendship with Saitama after her introduction, even showing up at his house with his other friends. Intrigued by how S-Class heroes have befriended him, she clearly wants to change herself and be a better person. She's persistent in her efforts to recruit Saitama, but resorts to persuasion or trickery. She also resort to bargaining information in exchange for Saitama giving Fubuki majority of the credit. She sometimes expose her softer side to Saitama.

After witnessing him defeat Garou and fighting toe-to-toe with Tatsumaki, she is inspired to become A-Class as she has faith in Saitama's fighting abilities. Though Saitama only sees Fubuki as an acquaintance, showing no progress have been made.

Tatsumaki
Fubuki's older sister and fellow esper. Fubuki highly respects Tatsumaki and desires to be acknowledged by her. Fubuki wants freedom from Tatsumaki deciding everything for her. Fubuki has an inferiority complex because of Tatsumaki always makes Fubuki efforts seem useless with her overwhelming psychic power. Tatsumaki highly criticizes Fubuki for having followers and losing to Demonic Fan and Do-S but still saved her from both monsters. However, while Tatsumaki is too proud to admit it she genuinely loves her sister.

Sweet Mask
Fubuki holds a certain level of respect and fear towards Sweet Mask's strength. Fubuki believes that she will never reach S-Class because of him. She describes him as a "monster", similar to her sister Tatsumaki.

Genos
Like Tatsumaki, Genos' relationship with Fubuki is rather strained, although arguably not as bad as Tatsumaki. The two don't often communicate with each other, but they don't appear to have a friendly relationship. This is seen when Genos rejects and slightly berates Fubuki's attempts to have him join her Blizzard Group. This tension also intensifies to the point of Genos threatening to incinerate Fubuki during hot pot dinner as she keep nagging Bang, Bomb and Dr. Kuseno to join her group.

Lily
Lily is her personal assistant and part of the Blizzard Group.

Speed-o'-Sound Sonic
While the two have not interacted with each other, Fubuki has respect for Sonic's abilities, stating he is as strong as a S-Class hero.
