Waking up in a strange bedroom in a dream world, teenager Haruto Tsukishiro finds a strange app on his phone. When he activates the program, an odd woman appears and tries to drag him to her realm. Luckily, a mysterious, white-haired girl severs their connection and helps him escape, revealing that the woman is a witch; however, their conversation is cut short. As Haruto enters the realm again, he meets an anthropomorphic, talking cat named Katsumi Kanzaki. While the witch's minions pursue them, the white-haired girl opens a door for them to escape.

After their ordeal, Haruto describes their savior—which only he can see—and Katsumi, the leading authority on dream world research, realizes that she must be "Lily," a being that resurfaces repeatedly across multiple dreamscapes. Hoping to leave the dream world through a blue door, they enter the witch's realm once again. Finding themselves in peril, Lily reveals the truth to Haruto: witches suffer from "Sleeping Beauty Syndrome," a coma-like sleep state induced by torment in their real world lives. Thus, they cannot wake until they are defeated in the dream world.

After finally defeating the witch and locating the blue door, Haruto and Katsumi say their farewells, promising to meet up in the real world. However, when Haruto exits through the door, he awakens in the dream world bedroom once more. Seeking answers, Haruto and Katsumi try to uncover the mysteries of the witches, Lily, and Haruto's own inability to leave the dream world.

People say 18if is like a box of chocolates: there are both good and bad parts and you won't know which one it is until you try. While I agree, I would rather compare it to an expensive box of luxury chocolates: all the flavours are exotic combinations, with ones such as broccoli-mango or truffle-chili. Initially you are turned off because you can't imagine these crazy combinations can possibly be good, but once you try some it becomes clear that they taste much better than they sound. Of course, there will always be some you dislike, but overall it's undeniable that a lot of well-placed ...

I don't usually write reviews, but this time I kinda ended up having commentaries for every episode, so I thought might as well post them here.

First off, the opening and the always-different endings were really fitting and good. I'm not usually a person that gives bonus points for a good soundtrack, but this time the soundtrack was either so good, or the rest was so bad that I think the OST is the best part about the whole anime. Heck, I discovered this anime from listening (and loving) to the ending of the seventh episode called "Too late" by Nene, Inori ...

Growing up is never easy, we all have our struggles along the way. Knowing that it will all be worth it eventually is what gives us the courage to persevere to adulthood.

18if tells the stories of multiple teenagers struggling with real-world problems in a very abstract fashion. Emotional turmoil is depicted through young women struggling to find happiness in the life they've been given; whether it be bullying, the weight of parental expectations, ostracizing, etcetera. These stories are played to resonate with the audience across 13 episodes, with varying degrees of success. The times it succeeds are rare but worthwhile indeed; even if as a ...
