Aiko Hatayama/Relationships

Hajime Nagumo
At first, she thinks of him as one of the students that she cares for. When he apparently dies she feels very responsible for it and does whatever she can to protect her students, even using herself as a bargaining chip. Later, after Hajime had killed Shimizu, knowing that he had done it for her sake, she becomes conscious of him as a member of the opposite sex. She later comes to accept that she loves him, although she's still troubled with the fact that she is older and his teacher.

David Zahler
He is a templar knight of the Holy Church and is in charge of Aiko's bodyguards while she roams the kingdom to use her powers to aid it agriculture. At first, he, and the other knights attempt to seduce her in order to make her more loyal to the Church, but they are moved by her kindness and have started being loyal and submissive to her. After learning that Aiko was partially responsible for destroying the Church's Temple and killing the Pope, David and the Aiko's other guards forgive her due to all they had learned from following her. He is now a devoted follower of Aiko and the new religion that based on her new title as the "Fertility Goddess".

Taichi Furukawa
Aiko's childhood friend. The two had a brother-sister relationship, but Taichi begins to develop feelings for her and finally confesses his love for her after she returns to Earth. Aiko could not respond to his feelings since she has chosen to be with Hajime. That put a strain on their relationship, but Aiko is convinced that they will be friends again someday.

Other Students
Aiko cares deeply about the safety of her students to the point that she was willing to threaten the King and the Pope after they tried to force her students to continue training after Hajime fell into the Abyss.
