Throughout Soul Eater NOT!, Hao supports his weapon Raid in his endeavors. In the beginning of the manga and throughout the anime', Hao bolsters Raid's bullying of others, even threatening Tsugumi Harudori when she attempts to draw away Meme Tatane from Raid's attempts at flirting. After being humbled by his defeat against Anya Hepburn, however, Hao behaves more appropriately and focuses on helping Raid become a better weapon.
