Review Detail of Nebel in Esper Harem in the Apocalypse

I really enjoy those east going harem romance stories, especially in modern settings. Personally I would prefer some less tragic background (since it's not time travel but alternate universe, I really feel bad for those girls) but it's fine I guess. writing quality also improved a lot since the last novel I've read from the author (well partly read, only read 300 chapters of Kings Mandate and lost interest then)... the wording of feelings still is a bit off from time to time, but overall quite good.
