Having defeated the monster, Vin sucked in a huge amount of air into his lungs to calm down. Although his heart rate was moderate, he needed to maintain constant respiration because that attack actually weakened him.
"VIN!"
The shout from two friends made him smile as he saw Andreas and Lucas runny in his direction with worry written all over their faces.
"Yo!" Vin smiled as he rubbed his neck sheepishly.
"That attack was awesome!" Andreas said with sparkles in his eyes.
"Yes!" Lucas joined. "Your fighting stance and that intense concentration…. I want to learn from you one day"
"I see," Vin smiled, trying to get over the real situation.
After this smile came a sudden frown. He remembered what Sebastian had warned before he unleashed that powerful blow.
Watching Vin's sudden emotion change, Lucas asked, "Are you okay?"
Noticing their worry, he forced a smile, "Yes…everything is okay. I'm thinking about something else."
