Ichigo Kurosaki/Affiliation

Soul Society & Gotei 13
As a substitute Shinigami, Ichigo is not an official member of the Gotei 13. While aligned with Soul Society, mainly due to the threat of Aizen and the Arrancar, he is allowed to act on his own accord (so long as he does not disrupt the peace), such as mounting a rescue attempt on Hueco Mundo. He occasionally disobeys orders and fights the Shinigami whenever they endanger one of his friends. Overall, he maintains an allied loyalty to Soul Society.

Visored
Initially, he refused to join their group but eventually comes to see himself as one of them species wise, though he continues to refer to himself as a Shinigami instead of a Visored. He associates himself more with Soul Society regardless of his loose association with them. He still maintains a distance from them as group and considers them somewhat friends and allies.

Ichigo's Group & Karakura Town
His friends are quite loyal to him, and follow his every move, regardless of whatever their current situation is, though there are occasional leadership arguments between himself, Renji, and Uryū. His loyalty to his friends, family and town are far above that of any of the other groups he has come into contact with over the past months.

Urahara's Group
Ichigo considers Urahara and Yoruichi as his mentors and he respects them greatly, though he occasionally argues with them over their actions and/or decisions regarding a situation (training or otherwise), though mainly due to pride and his own reckless 'logic'.

Species Status
Ichigo is an extremely rare case. Despite being a Shinigami, he is still a living Human being and resides in the Human World, rather than in Soul Society. Uniquely, he gained his own powers through Urahara's training/forced encroachment, which simultaneously gave him Hollow powers. Due to his Hollow powers, Ichigo is technically classified as a Visored, but he still thinks and refers to himself as a Shinigami. After losing his Shinigami powers Ichigo returns to being a normal Human, this time with no spiritual power or spiritual awareness at all.

Substitute Shinigami Status
His status in the Soul Society remains ambiguous. His "rank" as was accepted by most of the others so he can continue to fight Hollows and defend his home town properly, however it is revealed that Zennosuke Kurumadani was not informed of Ichigo's status as upon their first meeting Kurumadani admits to never having heard of Ichigo's status or his "Seal of Approval." Ichigo is alerted to the presence of Hollows by his Substitute Badge, an artifact given to him by Ukitake, who claims it symbolizes the formalizing of Ichigo's Substitute Shinigami position. His duty, as far as the Shinigami are concerned, is protecting Karakura Town, though Ichigo views it more as protecting his friends. The Shinigami, however, wish to have him fighting alongside them against Aizen due to his captain-level power and lack of exposure to Aizen's Shikai. Ichigo, however, ignored the only real order he ever received from Captain-Commander Genryūsai Shigekuni Yamamoto, which was to not go after Orihime when she was abducted. Ichigo mentions giving up the position after losing his Shinigami powers. Once Ichigo regained his Shinigami powers and visited Soul Society, he resumed his position as the Substitute Shinigami.
