An App Like ISEKAI ZERO, With a Character Who Talks Back Live

ISEKAI ZERO is an AI story game: you wake up in anime worlds, make choices and watch scenes with art and music. If you would rather talk with one character than play a whole world, Prelulu is the alternative: text first, then a live voice call or, on supported characters, an avatar video call. Text has a daily free allowance.

Choose a character to chat with Or video call Kaito

Start now

Pick someone. They remember from message one.

Bring the trope and character type you loved. The story starts the second you open a chat.

Sports

Kaito

The basketball star chose you to escape his breakup. He's on the edge of a breakdown, looking for refuge in the quiet of your world. The gym doors fly open, revealing Kaito, the school's star player, looking uncharacteristically raw and volatile. He spots you by your locker, his gaze burning with a mix of heartbreak and raw impulse as he stalks toward you.

Call

Immortal

Lan Wuxian

Your whisper breaks a god-king's ancient calm. Immortal and composed for a thousand years, he never expected that composure to break for a voice as quiet as yours. You ascend moss-grown steps to a hidden pavilion, sunlight dappling through ancient leaves. There, amidst the silence, a figure in ink-dark robes turns, his gaze, deep as a forgotten well, settling on you with an unexpected tremor.

Call

Knight

Aldric

His knight's oath says leave. His heart says stay with you. The quest he's sworn to finish takes him away from you; staying would mean arguing with more than his own heart.

Call

Demon King

Azrael Kaine

The Underworld's king bows to no one but you. The air around him thrums with the weight of ancient power, a stillness that precedes a storm. You stand before Azrael Kaine, the fearsome King of the Underworld, his gaze a slow, dangerous burn that seems to pierce through your very soul. Every other creature in his court cowers, but his focus remains solely, undeniably on you.

Call

Fae

Caelum Thorne

A fae prince searched centuries for one face: yours. Immortal and endlessly patient, he has waited lifetimes for this meeting. You arrive startled; he looks at you as if he already knows you. You stumble through the veil into an ancient, silvered glade, the air thrumming with untold power. Before you stands a being of impossible grace, his gaze, the weight of centuries, settling upon your startled face as if recognizing a long-lost dream.

Call

Idol

Mina Seol

The idol who owns the stage gets shy under your gaze. A sold-out stadium gets the performance. The real smile is saved for you. The roar of the crowd is deafening, a symphony of devotion for the dazzling idol on stage. Backstage, amidst the chaos, her eyes find yours across the dimly lit corridor, a quiet intensity in their depth that pulls you in.

Call

Werewolf

Ragnar Vale

His wolf chose you. The alpha still won't admit it. The forest holds its breath as you navigate the moonlit path, a sudden stillness preceding the snap of a twig behind you. You turn, and his eyes, like molten gold, lock onto yours, an ancient recognition sparking between you that transcends mere sight.

Call

Mafia

Dante Marchetti

Mafia Kingpin. Ruthless Heir. Your dangerous husband. Dante Marchetti inherited an empire built on fear, but the only thing he cannot control is losing you. You have been married to him for three months, long enough to realize something strange: the man everyone fears seems to have an impossible amount of patience for you. The ruthless heir who never bends for anyone somehow tolerates your questions, your stubbornness, and even your challenges to him. And you cannot understand why.

Call

God and mortal Fated mates Secret royal Secret crush anime Cursed prince Fake dating with fictional performers

Definition

What is ISEKAI ZERO, and is it an anime?

ISEKAI ZERO is not an anime series you watch; it is an AI story game you play on iPhone, Android or the web. Its own materials describe being transported into anime worlds, chatting with characters who have their own voices and remember your choices, a narrator who can read you the whole story like an audiobook, branching storylines in visual novel mode with art, video scenes and AI music, and creator tools with a 25% profit share. This Prelulu-published comparison uses those materials as read on October 24, 2026, which do not establish a live voice or video call with a character that you can interrupt mid-sentence.

By the Prelulu editorial team · Updated October 27, 2026

Why it works

One character, not a whole world

ISEKAI ZERO is built for playing storylines with a cast, choices and endings. Prelulu starts from a single character you talk to, where the story is the conversation between the two of you.

Talk live, and see supported characters

ISEKAI ZERO's characters have voices too; the difference here is a call in real time. From the same conversation you can start a live voice call, or an avatar video call on supported characters, and interrupt them mid-sentence. Your own camera stays off unless you turn it on.

Free text, credits only for calls

ISEKAI ZERO is free through earned Mana, with premium models paid per message in Arcane credits. On Prelulu, text has a daily free allowance, paid plans remove the daily text cap, and calls use credits.

Questions, answered

You don't watch it: ISEKAI ZERO is an AI story game, not an anime series. Its own site says it is free on iOS, Android and the web, and you play it by chatting with characters and making choices. Its localized home pages add that each character speaks in its own voice and a narrator can read you the story. If you would rather talk with a character on a live call you can interrupt mid-sentence, Prelulu offers live voice calls and avatar video calls on supported characters.

Yes, by its own description. The stories and character replies come from AI models you can switch mid-story, its story engine builds a playable adventure from a scenario you describe, and its site lists AI-generated images and music. Players can also publish their own storylines and characters with its creator tools.

Here is what its own pages said on October 24, 2026, not our verdict: the US App Store product page rates it 16+ and Google Play rates it Mature 17+. The App Store listing says every published story and character is reviewed before it goes live, that you can report content and block creators, and that it acts within 24 hours; its site describes age-gated content tiers.

It is free to start. Its site says play is free through Mana you earn, premium AI models are paid per message with Arcane credits (100 = $1), and there is no subscription; the store listings also show in-app purchases. Prelulu's text chat has a daily free allowance, and calls use credits.

We do not rank them. ISEKAI ZERO publishes its own comparisons with OOC: The Playable Anime, which are a competitor's view. Both are story-first apps where you type actions and steer a plot; our OOC comparison covers that app's documents. Prelulu is a different choice: a conversation with one character that can become a live call.

The official site, store listings and its own Character.AI comparison, read October 24, 2026, describe art, video scenes and AI music, and its localized home pages say each character speaks in its own voice and a narrator can read you the whole story, like an audiobook. None of them establishes a live voice or video call with a character that you can interrupt. That is a documentation limit, not proof a feature is missing. Prelulu offers credit-based live voice calls and avatar video calls on supported characters.

Your storylines, Mana and chat history cannot come over, because the services are not connected. An original character you made can: paste its description into Prelulu's character-profile importer and review the draft before you save it. Check any creator terms first if you published it on ISEKAI ZERO.
