The hero Heinrich, found in the alternate world accessed via the fourth Tartarus, he joins the party if you are on the Ilias route. Oh, and that strange mage he's with? Yup, definitely just an ordinary human mage.
Heinrich is only recruitable on the Ilias route, being mutually exclusive with Alicetroemeria. During the quest for the Six Orbs, you will be directed to enter the world beyond the fourth Tartarus to obtain the Blue Orb. You need to use a ship for this, but the mayor of Succubus Village won't allow you to use their ship that easily. Go to Heinrich in the inn and Ilias will talk him into joining the party.
[To be done later...]
The Legendary Hero Heinrich who was supposed to be sealed in Sealed Sinner's Prison somehow is still alive after Luka travels 500 years ago on their way they met him and Alicetromeria disguised as Black Alice from the past, unaware of her true identity. He is first encountered in Succubus Village (Alt) after Luka stopped Lilith and Lilim. He is only recruitable on Ilias route and Ilias tells him that she is the real Ilias. He offers to help Luka to get a boat transport on to Hellgondo Caverns and before they go to Black Alice's castle they made a stop at Remina and made their way to fight the Three Nobles of Black in the Gallery Section of the castle. Heinrich is aware of them and helps Luka defeat them and get the orb. He accompanies Luka after getting a message that the present timeline four kingdoms are being attacked by Alice's mother the 15th's allies on Grangold, Grand Noah, Sabasa and San Ilia to fend off Queen Mermaid, Queen Vampire, Queen Fairy and Spider Princess. If you have Alice and recruited Heinrich. He is glad that Alicetromeria will join with him on another world on an adventure.
Heinrich: “Let's go, Luka. We'll join forces and defeat evil!”
Ilias: “Heinrich... Is there no cloudiness in your heart which severs evil?”
Heinrich: “Yes, Ilias. There is no cloudiness in my heart at all.”
Ilias: “Do you swear to fight to the bitter end for the sake of justice at any moment?”
Heinrich: “Yes, Ilias. I swear by my sword!”
Ilias: “Will you not go on a rampage, even if it is something that displeases you? Is it really not that you cannot sleep from too much anger?”
Heinrich: “What happened, Ilias...?”
Heinrich: “This time, we're going to be adventuring together in another world... It's a very strange destiny, Alicetroemeria.”
Alicetroemeria: “Ufufu, it's wonderful... wherever we go, we shall conquer it together.”
Heinrich: “Ah! We'll fight together to the bitter end!”
Alicetroemeria: “Ufufufu...we'll stay together forever.”
Bonnie :“I see... I've learned a lot!”
With King of San Ilia:
King of San Ilia: “You are the hero Heinrich... After 500 years, there is no one who doesn't know of your fame.”
Heinrich: “That Heinrich is different from the one before you. I'm still in the middle of my quest to defeat the Monster Lord.”
Heinrich: “But what's with that form...? Are all priests mechanized in the world of the future?”
King of San Ilia: “If that were the case, it would be a very enjoyable dystopia... Unfortunately, I'm an exception.”
Heinrich: “There is no rival to the sword of justice!”
Heinrich is practicing his catchphrase...
Heinrich: “Secret Sword - Heroic Longsword!”
[Random 4 enemies take damage]
Heinrich: “This is a hero's stance!”
Heinrich struck his signature pose!
...But nobody was watching.
Heinrich: “Ilias, please protect us...”
Ilias prays and exudes a calm serenity!
[Party restores some health]
Heinrich: “Somehow, this thing got really attached to me... I'll let you have it.”
Heinrich presents a gift!
