What do you think about collaborating with me for the crossover with Madeline and her cast? I'm no artist, but we can write a script. I already came up with 2 fight events for this.
The first is the fight between Madeline and Erutika, and Erutika ends the fight similarly to Jotaro ending his fight with Josuke, although this fight is not as short, and that also depends on what Madeline does, if she decides to use magic against Erutika in foul play. If that's the case then Erutika will use a guardian spirit character that I completely forgot to mention in my previous comment (if you saw it already).
The second is Raiguko and his Bosozoku against Einen Kayne and the Worg. Raiguko fought and bested all of the Worg by himself using his gloves and pyrokinesis, while the female Cougar of the Bosozoku fights Einen herself since Raiguko doesn't like fighting girls, and he does know that Einen has pride and he doesn't want to insult it (if she even has pride).
Now on to the character I forgot to mention. This character's name is Teneha. She is a dragon that died prior to the canon story, and during the canon story, she merged her soul with Erutika's body, and she taught Erutika how to manifest and materialize her spirit, she became Erutika's personal guardian, saving Erutika's life time and time again using techniques similarly to Star Platinum. Erutika can summon Teneha by command, and while she has self awareness, she still follows Erutika's orders. She can also take over Erutika's body and transform into her living appearance, I.E., possess Erutika.
