I had fun reading this. The ending is what it should be, Yuuya got infected and rationally speaking, he should not be outside so it's good that the author did what he should do. Yuuya is peaceful now and also the cross hunter, he did went back down there cause he knows that he killed a lot of people so he deserved to not go out. I like how everyone was useful to yuuya and all their plans. I love this!
P.s. never thought the kid and the filipina girl would survive tho but dang that was great!
The baby of Arisu and Usagi is the mc of Alice no Border Road. I love the connections between the main story, this story and the last one cause the doctor from the last story is the brother of Mira (the Q of in the main story). He was able to meet the daughter of Arisu in the last story, dang. The author must havr put so much thought into making this.
