"How do you feel, my little brother?"
Eren inquired, drawing from his Sativa Stick and exhaling a billowing cloud of smoke into the brisk air. The two sped through the sky, leaving behind the desolation where Argo had transcended into the S-Rank. It was a hazardous place to linger.
Eren was certain that Argo's breakthrough had piqued the interest of formidable beings across the world. He had initially believed he had everything under control, yet he had underestimated the shockwaves generated by Argo's S-Rank Breakthrough Calamity, which reverberated throughout Anfang. No matter how busy the old monsters were busy in their affairs, they wouldn't miss something as astonishing as Argo's breakthrough.
Argo had assumed his majestic eagle form, a formidable demon beast. Perched on his back, Eren relished his smoke, battling the gusts of wind that tousled his hair and ruffled his clothes.
