For high school students like Shouichi Kamita, university entrance exams and the future are common concerns. It is also during this time in life that a mysterious emotion that vexes people of all ages may begin to weigh upon one's mind—love.

At this point in his teenage years, Shouichi finds three girls he could see himself having a future with: the ever-cheerful Hikari Tsuneki, who teases Shouichi without mercy, but actually has a softer side; the competitive gamer, Tooru Miyamae, who has difficulty communicating with others; and Shouichi's childhood friend, Kyouko Touno, the sometimes immature shoujo manga enthusiast. Seiren follows Shouichi's relationships with these three girls across three separate arcs, as their feelings grow from mutual interest and blossom into something more beautiful.

Seiren remains a hidden gem, often overshadowed by more mainstream titles. An initial glance at the reviews and its below-average rating made me apprehensive. However, after giving it a chance, I found it to be a refreshing departure from the norm. It's a testament to the old adage, "never judge a book by its cover" – or in this case, an anime by its rating.

From the outset, one might mistake Seiren for a typical harem, but it's far from that. Instead, it offers a novel approach to romance anime, presenting three distinct romantic paths with the protagonist, each with a different main heroine. Each arc ...

Mixed Feelings
Omnibus Format, is a type of story-telling that divides the whole series into multiple arcs each dedicated to a certain girl which the main characters gets a romantic relationship with. When an arc concludes, everything resets back to the beginning with an all new storyline and characters to follow. The most well-known series that features this kind of story-telling is Amagami SS which is pretty much the spiritual predecessor to our newest addition Seiren. Seiren, an original series made in collaboration with Studio Gakumi and Studio AXsiZ, aired this Spring 2017 is the newest series to feature omnibus format of story-telling. I personally think ...

Alright, since all the reviews here are full of bullshit and too long to read I had to make one of my own. The anime had potential but at around the first girl they messed up bad, it was a major turn-off and since then it only got worse. The anime is really cliche and generic. It's awkward and boring. The main character is useless like in most of the anime these days. I don't recommend it, but if you are bored and you have nothing better to do with your life then it sure is a good way of wasting your time.
