Basically, Otto is the main antagonist of HI3. I said antagonist, because while a villain actively wants ill for the main characters, he doesn't want that.
He was born in the XV century in Austria, and was the most frail and sickly kid, fifth born of House Apocalypse. He then mets Kallen Kaslana, who instead compliments him and believes in him, and from then on he idolizes her. When they were teenagers, they witness Kallen'a father die to save them, and since the oath of the Kaslana family states to protect the weaks, Otto is then terrified that Kallen will also die the same way. It's then that he unlocks Void Archives, trying to sacrifice his live to resurrect Kallen's father, but she stops him.
Ten years pass and Otto is willing to do anything, even less… ehtic things, to protect her. He also SINGLEHANDEDLY CURER THE PLAGUE. In the XV century. Then she finds out he's doing questionable things and that th Church of Schicksal, founded by the three noble familie Apocalypse, Schariach and Kaslana, is also very sus, nd she flees. In the East she meets Yae Sakura, and they fall in love. But Sakura become sort of a Herrscher (powerful emissaries of Honkai, the main threat of the world) and Kallen has to kill her. She then returns, and sends a letter of excuses to Otto (who never received it) stating that she was wrong to criticize him for what he did for her, when she did the same for Yae.
Once back, Schicksal sends her to death, Otto tries everything to stop it, asking her in marriage as last resort (he's always been in love with her, but never confessed because he knew she didn't feel the same, and only wanted her happy). But she refuses, saying that she doesn't want to live if it means being someone else's puppet.
So Otto, as the very last resort, asks for help his older sister Risa, who with their newphew was aiming at gaining power over Shicksal. She help, by releasing Honkai beasts during Kallen's death sentence.
She tries to protect the people, and ends up dying.
Otto kinda loses it for a while, goes around opening orphanages and taking care of kids, helps the rebellion take Schicksal back from Risa (who was doing even worse experiments), and ends up travelling to the East, to seach for that Immortal who defeated even Kallen, the strongest valkyrie, hoping to find a way to revive Kallen. He mets Sushang, stuff happens, this is the untranslated, unfinished Seven Swords visual novel (where he gets called Raksha and has an outfit similar to HSR)
Thanks to VA, he's pretty much immortal himself, but can't revive the dead
For 500 years he protects the world from Honkai. Valkyries exist thanks to him. If humanity managed to fight off Honkai it's thanks to him. All the technologies that allows Valkyries to fight are thanks to him. In the fifties he tries to clone Kallen, and has the clones fight each other, and one refuses to kill another. This clone is Theresa Apocalypse, which he adopts as his grandaughter, and the other is Amber (his secretary). At the same time, the First Eruption happens, and Welt Joyce is the Herrscher of Reason. This is the plot of the Anti-Entropy visual novel. In summary Welt Joyce (welt is literally the german word for "world") is on the side of humanity, but Void Archives does some tricks, and Otto ends up killing Joachim Nokianvirtanen's father, who inherits the core of the Herrscher of Reason from the dying Welt Joyce, thus becoming Welt Yang (Yang is from his mother). Yes, our Welt Yang.
Fast forward in the '90s, the Second Eruption happens, with the Herrscher of the Void, Sirin. They fight, yadda yadda, stuff happens, Welt dies but then resurrects, and not without difficulty humanity manages to kill Sirin.
Otto keeps the cores of the Herrchers, because he tries to find a way to make Herrshcers on the side of humanity. At this point, his plan is still to be able to capture the power of the future Herrscher of Death and use it to resurrect Kallen. But an encounter with the Will of Honkai, suggest that this is not the way.
Meanwhile a few years earlier, a descendant of the House Kaslana, Siegfried, has met Cecilia Schariac, they end up together and have a kid, Kiana. Cecilia ends up sacrificing herself to save all Siberia from Herrshcer of the Void, and while she was conscious of this, it was literally her choice, Otto made Theresa, her great friend, think that he killed her with a nuke.
Otto tries to find a way to control HoV powers with clones of Kiana, and one of these clones succedes. Little Kiana, of roughly 10 years, decides this clone in a tube must be saved, so her and her father sneak into Schicksal to steal it. Things go horribly wrong, and Kiana gets left behind, almost dead. Otto saves her, and since she doesn't remember anything, gives her the name Bianka Ataegina, aka Durandal. Meanwhile Siegfriend is with Kiana clone, and he gives her the name Kiana, grows her for a while and then leaves to avoid her Sirin personality to emerge.
She then goes to school to become a Valkyrie and meets Mei and Bronya. When Sirin ends up awakaning, Otto kidnaps her to Schicksal flying HQ (had she awoken at the school, it would've been a massacre).
She fights, and Himeko's sacrifice awakens Kiana's humanity. She hides away for a while and other stuff happens to other characters.
Meanwhile Otto has discovered, also thanks to Su from Previous Era and Durandal, what he has to do to resurrect Kallen. You see, he witnessed many, many parallel universes, and Kallen ALWAYS dies (this is a nod to GGZ).
But to enact his plan he needs HoV powers, and Kiana won't help him willingly.
So he devises a plan: in Kolosten, the old Schicksal HQ, he calls everyone. He sends a threat: he's going to reverse time, everyone who's currently in Kolosten will be safe, but everyone else outside will simply cease to exist as time gets reverted back to when kallen was alive. He taunts them all to come and stop him. This is actually a bait, and also his plan B. If the girls couldn't stop him, they'd have no hope against Honkai and future dangers, so 500 more years would be needed. His main plan is to trick Durandal and Kiana to kill him using theyr powers, so he could trascend existence itself.
All the "traps" he devised were actually personalized to each girl and her power, a sort of training. They fight, he gets killed, and manages to reach the Imaginary Tree. There, at the cost of his existence, CREATES new braches of possiiliy to let Kallen live.
His morally grey character has the best writing I've ever seen. His love for Kallen is something so… wonderful, it doesn't fit into romantic nor sexual, he doesn't want her for himself, heck, he doesn't even get to meet her once she finally has a new chance at life. He just wants her happy and safe.
