About This Game

Consider yourself warned and prepare your psyche: This is a slice of life game heavily focused on Netorare. In "My Best Friend Kouta", you take on the role of Eisen, whose life could be perfect if not for one detail... His best friend, Kouta, is extremely perverted. That wasn't a problem as long as Eisen was single. But now Evie, his new girlfriend, finds it strange that Eisen puts off so much to introduce his best friend.
As you explore all that Middleriver Town has to offer, date Evie and even make plans for a future engagement, Kouta will slowly corrupt Evie's mind, causing her to venture farther and farther into sordid desires, but that always existed.


Evie's moans, breaths, giggles and all other expressions are voiced for a more pleasurable immersion.

Use your cell phone for many things. Access the town's perv forum, receive messages, or even call Evie. But watch out, she can be in for embarrassing moments.
"E-Eisen? I... I can't talk right now, I'm with Kouta and...
Hmm... My mouth is full!"

Middleriver is an entire city to be explored. The cinema and Otaku Kingdom offer entertainment. You're part of the Scissor Corporation, but you can also make some extra money by working in the museum sometimes. Visit the Library to increase your Mental Energy or the Gym to increase your Physical Energy. Take your girlfriend out on dates at the restaurant or the park.
Furthermore, the city is populated by dozens and dozens of interactive NPCs. They provide secondary objectives, change dialogue depending on what's going on, give important information...
Last but not least, the city has a morning, afternoon, night and dawn system. Different things happen according to the time of day. Shops may or may not be open, NPCs may or may not be available.

Horniness scale
Each game gets a score from 1 to 5 hearts. Higher means more explicit adult content.
| Score | What it means |
|---|---|
| 1 | Raunchy / softcore — suggestive themes, light fanservice, or mature humor; little or no on-screen explicit sexual content. |
| 2 | Spicy but restrained — clear adult intent (nudity, strong innuendo, or brief suggestive scenes) without sustained explicit focus. |
| 3 | Clearly adult — recurring sexual content or nudity as a meaningful part of the experience, but not the sole focus of the game. |
| 4 | Strongly explicit — graphic sexual themes, extended explicit stills or text, or gameplay built heavily around adult situations. |
| 5 | Explicit and often animated — graphic sexual content that is frequently animated or interactive; core to what you see and do in the game. |

Love the visuals and the side missions. The character banter is top tier.

Story is solid and the combat feels great, just wish there was more UI customization.

I keep coming back after every update. The new scenes were worth it.
