Solution Epsilon/Relationships

Ainz Ooal Gown
Solution shows absolute loyalty to Ainz and the Forty-One Supreme Beings. After finishing her mission with Sebas, she was beaming with happiness and nearly humming with joy. In Sebas' opinion it was not because she was returning home at last but because she had completed her master's orders. She, along with several other Guardians, were prepared to kill Sebas without hesitation if he was proven to be disloyal towards her master but in the end it was unnecessary.

Sebas Tian
Sebas is Solution's superior in which they show a superior-and-subordinate relationship. Even with this fact, she did not hesitate to report his mistake to Ainz or stand up against him.

Yuri Alpha
Yuri is the vice-leader of the pleiades and Solution's superior. Solution is seen as a bad younger sister by Yuri because of her sadistic and evil personality.

Lupusregina Beta
Solution has a friendly relationship with her sister and colleague Lupusregina. They worked together during the events of the demon invasion in the Kingdom as Jaldabaoth's servants.

Narberal Gamma
Solution is jealous of her due to her closeness to Ainz.

CZ Delta
They share the same feeling of jealousy toward Narberal, due to her closeness to Ainz.

Entoma Vasilissa Zeta
Solution has a friendly relationship with her sister and colleague Entoma. They share the same hobby of eating humans. They worked together during the events of the demon invasion in the Kingdom as Jaldabaoth's servants. They share the same feeling of jealousy toward Narberal, due to her closeness to Ainz.

Lastborn of Pleiades
Lastborn of Pleiades is the leader of the Pleiades Seven Sisters, thus Solution Epsilon's superior. While Solution doesn't like humans, the Lastborn of Pleiades is an exception, mostly because Solution doesn't see her as a human, since she is immortal. It has been shown that Solution cares about her, defending her when Ainz asked her if he should exile her from Nazarick because she is human.

Albedo
Albedo thinks Solution has a low class hobby for sharing the same interests as Shalltear. She was disappointed when discovered she couldn't recruit Solution to her side.

Shalltear Bloodfallen
She supports Shalltear's love for Ainz and they both share similar interests.

Demiurge
Solution agreed with Demiurge that killing Tuare was the best option to take. During the events of the demon invasion, Demiurge wanted to put Solution in the reserve team, but placed her alongside Sebas due to her superior detection abilities to find the kidnapped Tuare. When Solution asked about what to do with the humans who kidnapped Tuare, Demiurge replied that if she were to leave alive any of them, he would kill her.

Solution worked alongside Demiurge in his plan to make Momon a national hero. Solution played the role of one of Jaldabaoth’s servants and fought against Nabe alongside Lupusregina and Entoma.

Tuareninya Veyron
When Solution saw Tuare for the first time, she thought that Sebas brought her as a present for her. She didn't liked the idea of curing her, even though Sebas was the one who asked her to do it. She saw her as a useless human and thought that Sebas was disobeying Ainz's orders by keeping her. When talking with Ainz about what to do with Tuare, she had the same opinion as Demiurge, that killing Tuare was the best choice to make.

Zach
Zach was a servant hired to drive the carriage. Solution asked Sebas and Shalltear permission to have him. When Zach led the carriage to an ambush, he was surprised and scared of seeing the members of the Death Spreading Brigade being killed by the Vampire Brides. Too scared to flee, Zach was led a little bit away by Solution whom Zach had hoped to rape after the ambush, but instead he was ingested by the slime monster. He was slowly digested alive, his agony lasting two days.
