Saikin Koi Shiteru?

About

Saikin Koi Shiteru? is a visual novel where you play a 17-year-old student who transfers to a new academy and immediately falls into a suspiciously placed pool. This leads to meeting Saikin, tiny creatures visible only to you that live inside everyone else. You use them to subtly alter emotions of classmates and teachers, balancing school life with relationship choices. Dialogue options and Saikin manipulation drive the story, with outcomes shaped by how you blend social skills and microbial trickery for, ostensibly, noble causes. The game’s mix of mundane high school drama and absurd sci-fi elements creates a peculiar charm. Players navigate awkward interactions with tools that feel both ridiculous and oddly strategic. Though released in 2009, its niche humor and creative mechanics have kept it memorable for fans of unconventional dating sims. The juxtaposition of microscopic influence and human connections offers a strangely endearing take on the genre.

Storyline

The 17 year old nameable heroine transfers to Seiran Academy and falls into a deep pool that’s just sitting right at the entrance, and meets some…mitochondria? It turns out that everyone she meets has them but only she can see them. She names them Saikin (bacteria) and uses them to manipulate other peoples feelings (with…good intentions).
