While on his patrol of the city, Eraserhead investigates the infamous League of Assassins. During his investigation, he is sent an invitation by none other than the League's leader: Ra's al Ghul. Eraserhead then makes his way to the one of the League's compound where two of Assassins escort Eraserhead to the Chamber of the Demon where Ra's al Ghul greeted the Pro Hero.

Ra's: Greetings, Shota Aizawa. I am Ra's al Ghul, the Head of the Demon and master of the League of Assassins. I've been expecting you. 

Eraserhead: You better have a good reason for calling me here. I have work to do.

Ra's: This world is sick. A cancer has taken hold of society. A cancer that must be wiped away. Heroism alone won't save this world. To truly save this world, men of vision must do whatever is necessary to save it. Join me, and together we will wipe this world clean. 

Upon hearing this, Eraserhead was caught off guard by the fact that a Villain tried to recruit him. 

Eraserhead: You must either be bold or reckless. Maybe both. I don't intend on joining some madman's crusade. You're misguided and I'm taking you in. 

Upon hearing this, Ra's simply chuckled. 

Ra's: I suggest you reconsider. The blood of the demon has allowed me to live for 600 years. Imagine the good that you could do with such a gift. We could become powerful allies, Aizawa. We could become a force of good. A force of change. We can save this world from the evil that is destroying it.

Eraserhead: This world is far from perfect, but destroying it won't make it any better. 

Ra's: If that is what you wish, then I'm afraid we're at an impasse. You disappoint me, Aizawa. We could've accomplished so much together. 

As Ra's said this, smoke bombs ignited and Eraserhead was ambushed by a group of Assassins. Eraserhead was able to dodge the initial ambush and attack the Assassins. As he takes down the last of the group, Ra's stood up from his desk and pulls out a sword. 

Ra's: Now, only one of us can leave this chamber alive. Are you man enough to face your better?

Eraserhead: We'll see about that.

As Eraserhead said this, Ra's al Ghul began attacking the Pro Hero with his sword. Easerhead was able to dodge the attacks and grab one of the Assassin's swords. As the two locked blades, Ra's chuckles. 

Ra's: Impressive, Aizawa. Most impressive. But I'm afraid you're outmatched. 

Ra's then presses the attack and lands a couple of non lethal slashes on Eraserhead. Easerhead was able to block the next attack and follows by striking Ra's in the face with the hilt of the sword. Ra's was able to parry Eraserhead's next attack. 

Eraserhead: Give it up, Ra's. You can't win.

Ra's: I have knowledge which is alien to you, for I have tasted food fresh from dark fertile soil, and I have filled my lungs with untainted air, and I have quenched my thirst with water clear as the first day of creation, and you have not -- because you can not. Those things do not exist on this world any longer. They have been destroyed by man's lust for dominance -- a lust I know well, for at times it all but consumes me. All is corrupt, all is sick, all is dying. As am I. As are you.

In that moment, Ra's and Eraserhead engaged once more in a sword duel. As Ra's kept Eraserhead on the defensive as the Pro Hero was unable to break through Ra's defenses. 

Ra's: Do you think this matters? You are but seconds in my life! Only I know humanity for what it truly is! Only I can see the grand movements of generations! Only I, undying, can live within this world and protect it from itself! 

Eraserhead: I won't let you harm an innocent life! 

Ra's: In the new world, all peoples will be united, every race, every faith, every creed will find common purpose... our world is not for everyone. Only those who prove their worth will enter it. The rest will be purged... and if nine hundred and ninety-nine must perish for every one who lives...so be it!

Ra's attacked Eraserhead with precise savagry. Despite being outmatched, Eraserhead proved stubborn as he kept parrying the atacks from Ra's. Eventually, Eraserhead was able to break through Ra's's defenses and broke the sword with his own. Eraserhead then uses his Combat Scarves to subdue Ra's. 

Eraserhead: It's over, Ra's. You're finished. 

Despite being beaten, Ra's shows no sign of concern. In fact, Ra's simply laughs quietly.

Ra's: As you know, I am cursed with a love for emptiness...desolation. It is a beauty to which my soul responds...as pure, as untainted as the deserts of my birth. I deem it my mission to purify this planet, to restore it to its former beauty...a mission I will brook no interference in. This is a setback, not a defeat. The advantage is mine. I have eternity...and you must win every single time...while I need win but once. 

As Ra's said this, a smoke bomb bursts and blinds Eraserhead. When he recovers, he finds that Ra's has escaped. Eraserhead attempts to track him down, but finds no trace. As he searches the compound, he finds it completely empty.

Eraserhead: Damn. He got away...

With that, Eraserhead was forced to put his investigation on Ra's al Ghul and the League of Assassins on hold. He then leaves the compound and resumes his patrol of the city.
