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.

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.

This review contains mild spoilers.

Seiren offers an insurance policy against the inherent risk of harem anime. You don't have to worry about best girl getting her heart torn to shreds by some milktoast dude choosing the worst possible option. Instead, the milktoast dude chooses every single option in different timelines. Everybody wins!....or do they?

What Seiren gains in having multiple routes it loses in meaningful character progression. You won't feel the ultimate satisfaction from watching two lovers grow together over a dozen episodes nor is there any conflict to set up an emotional payoff. This problem is further compounded by boring character designs barely distinguishing ...

Teenage hormones are a powerful thing. The trials and tribulations we went through in our adolescence involving relationships and such can seem trivial by comparison to our current lives, but when we were in the moment they seemed so monumental. Whether it was timidly asking a girl out for the first time, or the lucidity and nostalgia of a summer romance, not much can compare to our teen years. Seiren randomly popped up on my radar before the winter season started (probably due to the plethora of attractive female character models), and after its conclusion I can assuredly say two things:

As a married man in ...
