Story
The story will count with twenty episodes, roughly seven hours to pass story in normal means, and nine hours with the secrets.

The game deals with an ancient artifact named "Volt Crux", whose power is limitless, however, the bad guys as usual are trying to get the artifact for their own means. The heroes must help Lumina and Mercury to avoid a bigger disaster, but is too late, as "Volt Crux" gained sentience and now counts a death sentence to the universe of In-Verse.

Trivia

 * This is the second largest crossover roster of In-Verse's history, the first being the 10th anniversary game Legends.
 * This is the first In-Verse Heroes game with a proper story, despite being the average crossover type, it will have no talked dialogue except for some scenes like The Subspace Emissary from Super Smash Bros. Brawl, instead, and the rest is text-based.
 * Some of the unorthodox selections, such as Sage, Ike, Echidna, Yuri and Hilda, and clones such as Kali and Ignis, are secret characters.
 * Victoria, Genesis and Jet Dark are the only main characters from games with more than two representatives that aren't final bosses in their representative franchises. Instead the spot belongs to Solaria, Mondo and Darkness (the first is Victoria's servant and a major rival to Vlad in DMotNIII, the second was the final boss in the first Arcana Warriors game and the latter is the antagonist of the Neo Formula Racing expansion Xtra.)
 * The story mode will be shorter than Versus, lasting 7-9-hours, 31-hours less than Versus' 40hrs, and the 50-hour Legends.
 * There's a hint that Lumina and Mercury are secretely engaged, according to future characters such as Devil's Eye party, Sibylla, Balder, Ignis, Battle of Zero reps, the Neo Formula quartet, etc.
 * And that's apparently the reason behind Lumina wearing an eyepatch in this game and in Versus.
 * However, due to their age difference; Mercury is more than hundreds of years old and Lumina is only in her mid twenties, but her real age is unknown. This causes a personal conflict between the two.
 * Kali Chrome is the only character of the past/present that knows the thing, but prefers to keep matters to herself.
 * About the status of some characters, Pauly-kun, said like in the games, some of them are dead who never return or some of them disappeared and others make cameos, the list of status of the following characters is:
 * Anne Teague (Versus): Injured, but appears in Story Mode.
 * Galileo (Starry Sky Story): Retired, but works as Obscura's Minister on Vivid.
 * Riza Ena Hallbard (Starry Sky Story): Dead, the Versus one was a clone.
 * Coldfire and Blitz (Starry Sky Story): Killed.
 * Marthe de Rais and Justine aka Chernobog (Legends): Both are Missing.
 * Adele and Ikaruga (Legends): Cameo as drivers in story Mode.
 * The Warriors of Chaos (Versus): All four are dead, albeit Kamui's body was frozen in time.
 * Pandemonium (Versus): Sealed after the events.
 * The Clouds of Heaven (Starry Sky Story): Died within Riza Hallbard.
 * The Alternate Costumes and Characters were last-minute additions, the last one to be added was Chiaro Argiaren from Advent.
 * The game suffered an upgraded rating in Japan as result of some animations and swearing in the quotes, first print copies had the CERO "B (12+)" ratings, while current ones include the CERO "C (15+)" ratings, the Western and European ratings are left unaffected.
