    Solid setup
    This review contains spoilers. Very interesting story with a lot of mysteries in the first volume. Hoping the next one releases in a decent time. The main character is cute while the sister does her job of being pretty much a jerk to the heroine haha. Curious to see how the relationships all around develop.

    Has potential but also plot holes - kinda average
    I'm rating this four stars because I don't think my hang-ups are necessarily a reason for others not to give it a try if the story seems interesting to them. But if I was to rate it solely on my short impression, it'd be a 3 star rating.

    I started reading this as a fan translation elsewhere before I could find an official one to support. I gave it a fair shot but didn't get super far in it before I decided it just wasn't my cup of tea. There are several plot holes that are hard to ignore, at least for me, and I wasn't fond enough of the presumed ML to push through it. And he wasn't the only one, there were also a handful of other characters whose motivations and personalities just didn't seem to have a lot of substance. The art is nice and the story does have potential, but I just wasn't able get real engaged due to the things that bothered me.

    5巻、待った甲斐がありました!!
    This review contains spoilers. 絵が綺麗で、惹き込まれるストーリー。大好きな琴子先生原作のコミカライズ作品です。前巻の発売から待ちに待っての異世姉5巻の発売♡嬉しいです。早速読みました!!ノアがイチカに対して甘えん坊になってる。出会いの最低な印象から変わり、ストレートな愛情表現にぐっときました。神殿長のレヴィちゃんの本当の姿を見たイチカ、びっくりしすぎてすごい後ずさりしてたのに笑ってしまった(笑)本来の姿のレヴィエンさまが好みすぎて、めちゃくちゃかっこよくて見とれてしまいます♡♡♡元の世界に帰る方法が、世界の崩壊を防ぐこと。ずっとイチカになりたかった姉カレン。カレンは、イチカだけを元の世界に返そうとしていて、心の中でイチカ、早く気づいて!!と叫びつつ読みました。それにしても、セシルも子供の頃鏡でイチカと話していたのには驚いたなぁ。5巻、謎がいろいろ分かった巻でした。もう、続きが気になってしかたない。早く次巻が読みたいです!!
