Synopsis

Having lost her memories of the past three years, Arisa Suzuki is surprised to learn that Mari Satou is her girlfriend. While Mari worries that she no longer loves her, it is obvious from their reunion that it was love at first sight for Arisa once more. Wanting to rekindle their bond, Mari endeavors to remind Arisa about their experiences—from their first meeting to their first kiss.

Yet, the task proves to be difficult, as Arisa can no longer do a multitude of things. This becomes prominent when Mari describes the sex life the two shared. In the past, Arisa was very dominant in their relationship, often being the initiator. However, lacking the experience she once had, Arisa is now more timid than the person her girlfriend illustrates, causing her to envy her pre-amnesiac self.

Thus, the two begin to reconstruct their relationship, devotedly putting in as much effort as they can for the one they love most.

What an interesting premise! I generally am not huge on 4-koma manga, but this was pretty good overall! Just know that this manga is pretty simple.

​First, there's Arisa, the hyperactive and open amnesiac. She has two clashing aspects of personalities, and that fits perfectly with the premise. The perverted and aggressive past self lingers with the previously sexually shy current, leading to plenty of hijinks and conflicts. She works well with Mari, the passive but passionate lover that seldom took the initiative. Plenty of interesting side characters come around to exploit these traits and help out the lovers as they figure out how to get ...

Akarui Kioku Soushitsu is pretty much exactly what it proclaims to be. The main character has amnesia and proceeds to fall in love with her partner all over again at first sight. She's goofy, cheerful, playful, and just wants to see what happens next. This story really emphasizes how important it is to have someone positive around, because she is continually inspiring other characters with her positive attitude and awkward straightforwardness.

It has its heartfelt moments too. There were plenty of things that I, as a lesbian, could identify with, but it's not like. Tear-jerking. It's more sweet than anything.

Anyway, really the whole thing is about ...

Preliminary (41/67 eps)
I really, really wanted to like Bright and Cheery Amnesia, but I just don't.

As a fan of gay things, this one's not for me. I just... do not understand the Japanese sense of humor, and it overshadows the gay by a landslide in this one. At least... I assume it's meant to be funny? If not, why does this exist? There's nothing actively offensive about the premise to me, but it's yet another bland, hack-comedy 4-koma piece, featuring a level of humor about equal to that of a Garfield comic.

But this one's different, I hear you say. This one has lesbians. Alright, we can ...
