Why does Kyotoshi call Soshika “Lyika”?
It’s a Hekshanian way of making cutesy pet names usually used by family members for the youngest or between lovers. The last part of the first name and the first part of the last name are combined. Kyotoshi’s for example would be Lyoshi. Zara Nikko’s would be Nikra. Juu Dyrano would be Dyrau and so on… It indicates affection and closeness. Kyotoshi still feels close to his sister, even if she doesn’t want to talk to him.
