I think what's creeping me out is continuity of consciousness? "Summon" implies "this critter was over there, and now it's here." But the way Gamesverse summons were explained in the infodumps, they don't exist when they're not present (as opposed to, say, the Wolkenritter, who are theoretically running full-time on Reinforce's systems whether or not they have incarnated mana-construct bodies and are just in "sleep mode" when not in use). So, there's no "Garyuu" per se, but "a series of Garyuus, each of whom has a life span of 'from when I summoned him to when I dismissed him.'"
Ergo, the creepy part. I found Garyuu being a simulated non-sapient intelligence run by the magical program manifested within the spell encoded in the Alpine bloodline
sad 'cause I kind of liked Kamen Rider Bug. He was a big sweetie to Lulu. But the idea that he's a sapient program is chilling, since the summoning seems a lot like "I'm creating sapient life! And then I'm snuffing out my creation because it's more convenient not to keep on with the upkeep!" Which, if I remember correctly, is part of
canon familiar creation that Gamesverse decided to do away with because, well,
it's horrifying.
Edit: Please explain why I'm wrong.
