Tsugumi's Links
AU: Tsuki is Tsugumi's older twin sister. The pair are inseparable after enduring many hardships in their childhood, eventually conspiring together to murder their parents. They are both quite protective of one another, and Tsuki gets stressed if Gumi is away for too long.
Initially meeting in an online chatroom, Kei was catfished by Gumi and quickly fell in love with the other inkling. Kei was aware that Gumi was manipulating him into doing things, but enjoyed that aspect of their relationship and the monetary rewards that came with it. After talking to Tsugumi for quite some time, Kei was able to figure out Gumi's true identity and stalked him for a while before confronting Tsugumi in an internet cafe and confessing his feelings. Kei doesn't care that Gumi isn't the person he said he was online, thinking that the actual Tsugumi is significantly better. He is obsessed with Gumi and everything revolving around Gumi. Kei always follows Tsugumi around, sitting at his feet when Gumi is on the computer or trying to sleep on the floor in Gumi's bedroom. He believes that he is below Tsugumi and doesn't deserve the luxury of his affection. He will do anything that Tsugumi asks, including killing people and appeasing Gumi's religious fascinations.
AU: Axton and Tsugumi have a long-standing history, initially meeting when Axton was investigating Gumi's father. Tsugumi and his sister turned up on Axton's doorstep and offered an allegiance. The pair went to Russia together to disassemble a prominent pedophile ring, in which they become quite close. The two get along quite well, both being the quiet ones of their group and Axton will often seek Gumi's company and advice on matters.
