Sentino Inc. Press Release: Towards an Infrastructure for an Era Where Characters Can Do Business

Sentino Inc. (Headquarters: Minato-ku, Tokyo; Founder / CEO: Chris Chen; Representative Director: Senchi Kara) has announced "Sentino," an AI character creation and operation platform for IP holders and individual creators.

Sentino is not merely a "tool for creating" AI characters.
It is an "AI character entertainment agency infrastructure" that enables creators and IP holders to build and manage relationships with fans centered around characters, and to continuously generate revenue.

◆ First Public Unveiling at an Event

On March 30, 2026, the product demo was first unveiled at "Voice AI x Anime: How to Create Next-Generation Characters," an event linked to AnimeJapan Week.

Currently, Sentino is recruiting participants for a closed beta test targeting creators and IP holders.

◆ Three Giant Markets Are Already Moving in the Same Direction

Users emotionally engage with and continuously pay for "virtual beings with personalities"—this consumption behavior has already been proven in multiple markets.

In the game market,

as exemplified by "Love and Deepspace" and "Ensemble Stars!!," monetization based on the relationship with characters is established.

In the VTuber and virtual idol market,

characters are established as continuously active IPs, forming an economic sphere centered around super chats, merchandise, and communities.

Furthermore, in the real idol/influencer economy,

a management model of "nurturing talent, organizing fans, and monetizing" has been established.

Common to these three is the fact that

"people continuously pay for beings with personalities."

However, there is something missing across all these markets:

It is an integrated infrastructure that can massively "create, operate, and monetize" characters.

◆ The Fundamental Problem Is Not a "Tool" but the "Absence of Infrastructure"

Creators and IP holders understand characters most deeply.

However, current AI solutions presuppose API and engineering knowledge, creating technical barriers before creativity.

Also, if a general-purpose LLM is applied directly, the problem of characters making "out-of-character" remarks—the so-called character breakdown—is unavoidable.

AI chats, virtual idols, and role-playing services exist individually.

However,

a platform that integrates all of these—where creators themselves produce characters, continuously manage relationships with fans, monetize them, and have multiple characters exist in relation to each other—has not existed until now.

Sentino is building this "missing layer."

◆ What is Sentino: A Foundation for Anyone to Have an "AI Character Agency"

Sentino itself does not own IP or directly operate characters.

It provides the foundational capabilities for creators and companies to establish their own "AI character agencies."

The platform consists of the following three layers:

Sentino (Foundation Layer)

Provides the AI infrastructure necessary for creation, operation, and distribution.

Agency Layer (Companies/Creators)

IP companies, game companies, VTuber agencies, and individual creators create and operate characters.

User Layer (Fans)

Pay for interaction with characters.

The revenue model is simple:

User payments → Creator revenue → Sentino collects infrastructure usage fees.

◆ Not All IPs Can "Make Money"

Sentino clearly defines IPs suitable for long-term AI character operation.

For continuous monetization to be established,

characters must have "value worth continuing to talk to."

The evaluation axes are the following three:

The ideal IP profile is a story-driven IP with depth in its worldview. This includes long-form anime/TV series IPs, story-driven game IPs (representative works from Capcom, Falcom, Atlus, etc.), and long-running manga/light novel IPs.

Conversely, IPs that are consumed once and completed (characters are uniform, worldview is closed, no sequels planned) are not suitable for long-term AI character operation.

◆ Agent Matrix: Technology to Prevent Characters from Being "Isolated"

Traditional AI characters have been limited to a closed "user x 1 character" relationship.

Agent Matrix changes this premise.

By defining relationships between characters (e.g., conflict, cooperation, romance, mentorship),

multiple characters interact in real-time, and the world begins to move autonomously.

Users enter not a chat, but "the world where characters exist."

This signifies an evolution from

multi-agent dialogue → character relationship network → digital reconstruction of the worldview.

Sentino's long-term vision aims for every IP to have its own "gateway to the world" on the platform. If traditional metaverses are models of "building a 3D space and waiting for people to come,"

Sentino envisions an approach where the network of character relationships itself becomes the world.
