Hymn.

Hymn takes fascination in Ruru and likes to observe him from a perspective. Behind recording data of this mischivous robot, Hymn enjoys him and the company. Robot buds FTW.

Hymn finds Aoi to be a strange creature and often times catches himself watching her very closely, especially as she interacts with items or people. Though he doesn't speak to her much, he wishes to get closer and learn more about her and her species.

Miki sort of popped into Hymn's life at random. She can speak to him within his mind as he found she was a computer virus with sentience, which isn't a complete bad thing. He finds her very unique and interesting and does not mind the conversation here and there.

Hymn learnt about XP as he snooped through computers and found it lying around in files. He enjoys connecting himself to said computers and talking to XP through there, learning about its purpose and what it does for people. Though XP is not much outside of a hacked program, he heavily enjoys his time listening and learning more about computers.
