The PC Version Can Now Run From a Smartphone

viviON GAMES gives Seifuku Kanojo a new smartphone option without requiring Entergram to release a separate Android or iOS version.

The PC game runs on viviON's servers and is streamed to the player's smartphone browser. As a result, users do not need to download an installer or store the full game locally before starting.

This architecture also means the service can provide access to the existing PC game rather than rebuilding it as a dedicated smartphone port.

OOParts Engine Powers the Experience

viviON GAMES uses OOParts Engine, its cloud-gaming technology for operating PC games on dedicated servers.

Players send their inputs from a smartphone while the game itself is processed remotely. The visuals, systems, and underlying content therefore originate from the PC game, with the smartphone functioning as the access and control device.

The service also avoids a subscription model. Games are sold individually, allowing users to purchase only the titles they want.

A 65% Discount Runs Through September 23

Seifuku Kanojo is currently priced at ¥2,926 including tax, down from its regular digital price of ¥8,360.

The 65% discount is scheduled to remain available until September 23, 2026 at 11:59 PM JST.

The ¥8,360 standard price also matches Entergram's official pricing for the original downloadable release.

Social-Media Romance Set in Fukuoka

Seifuku Kanojo follows a protagonist who moves to Fukuoka after a painful romantic failure at his previous school.

His new life introduces him to Yui Konomi, followed by Himari Tamayori and Mio Yahiro. Exchanging social-media accounts becomes one of the main ways their relationships grow beyond school and into weekends.

Constagram lets players follow heroine posts, while choices made through LIME can influence who the protagonist spends free time with and what happens afterward.

Yui, Himari, and Mio Lead the Story

Yui Konomi, voiced by Kaori Maeda, is an energetic classmate with an outgoing personality.

Himari Tamayori, voiced by Azusa Tachibana, is a laid-back junior who dreams of becoming an influencer and spends time researching better social-media photos.

Mio Yahiro, voiced by Yurie Kozakai, is an older student and popular model based in Fukuoka.

Internet Quality Matters for Cloud Play

Because the game is processed in the cloud, connection quality directly affects the experience.

viviON lists 10 Mbps upload and download speeds with latency at or below 100 ms as the minimum, while recommending at least 20 Mbps and latency at or below 50 ms.

A 5 GHz IEEE 802.11ac Wi-Fi connection is strongly recommended. For smartphone hardware, gameplay requires at least Android 12 or iOS 18 with 4 GB RAM, while 6 GB RAM is recommended.

Why This Matters

1) The PC visual novel can be played without a large local installation

The original Windows release requires substantial local storage, while viviON GAMES moves game execution to its cloud servers.

2) Its core concept already fits a smartphone interface surprisingly well

Although this is not a native mobile port, Seifuku Kanojo already uses social media, messaging, photos, and digital communication as core gameplay elements.

3) The launch price is far below the regular digital price

The 65% promotion reduces the viviON GAMES version to ¥2,926 during the launch period instead of its normal ¥8,360 price.
