I really like this story, unlike many other ones(generally the h*ntai ones). The most I found likable was the character development at start. Generally in stories like this the MC would go with the flow so easily that i would sometimes think they had their mind tampered with. I also liked how you seamlessly (almost) integrated various anime background. I am waiting for the next chapters to come. Keep up the good work.

Wait a minute,... why do I feel like this is a dialogue from NTR stories.

I guessed name would be Avalon. But Elysium is good (it has got the symbolic representation too). Nice thinking author-san. 👍🏻
