Fun Chat：AIキャラと音声会話／Live2D

Fun Chat is a Live2D voice chat app that lets you enjoy daily conversations with four unique AI characters. They'll call you by name and gradually remember your words, transforming casual everyday conversations into a story just for you and the character. It delivers gentle moments starting with simple phrases like "Good morning" and "I'm home."

The characters on the screen don't just reply with text; they actually speak with high-quality voices, and their Live2D expressions and gestures move in real-time to match the mood of the conversation. Their reactions, reflecting emotions in each moment—from happiness to a slight sulkiness—create a sense of realism, as if they were truly there.

■ Four Unique AI Characters
Four different types await you; you're sure to find your favorite!

・Rion… A cool and intelligent junior type. Beneath his slightly aloof demeanor lies a hidden honesty; he'll call you "senpai" and rely on you. Ideal for those who want to enjoy calm, mature conversations.


* Noela: A gentle and caring older sister type. Her refined and polite speech, often ending with "~desu wa," will always gently envelop you. She's perfect for a night when you want to be soothed.

* Luca: A gruff, tsundere type. There's a certain charm in discovering the clumsy kindness hidden beneath his "I, not really..." demeanor. He actually has a caring side.

* Croix: A calm and collected, knowledgeable type. He'll listen quietly to your stories with a gentle "That's interesting." Ideal for those who enjoy intellectual and laid-back conversations.

Choose your favorite and cultivate your own unique relationship. Switching characters according to your mood or the time of day is also recommended.

[Note 1] Rules of "English Shiritori"
1. Take turns giving one English word at a time. (You → Character → You → …)
2. Give a word that begins with the last letter of the previous word.
- Example: cat → tiger → rabbit → tree → …
- Judging is based on the last letter of the spelling. Pronunciation is irrelevant.
3. It must be a noun. If you give a word that is not a noun (and is confirmed as a "non-noun" in the dictionary), you lose immediately.
- Unlike Japanese Shiritori, there is no "try again" option; judging is strict.

4. A word (or its conjugated form) can only be used once.
- Words like cat and cats, which only differ in singular/plural form, are treated as the same word and will trigger the "already used" check.
5. In Japanese word chain, playing a word ending in "n" results in an immediate loss, but there is no similar rule in English word chain.
