"Nee-san." Fumio calls out to Sayuri who despite getting over her shock at everything she witnessed earlier, is still muddleheaded with questions that have immediately brewed in her mind.
"Y-yes…" Sayuri responds in panic.
Looking at Fumio, who she now assumes to be at least a high tier B-Class Superiori based on the speed he displayed earlier, she no longer certain of how to act.
"I'm still your brother." Fuimo says, a bit bitter of Sayuri's change in attitude.
"Of course." Sayuri nods, feeling a bit relieved by Fumio's words.
Seeing that Sayuri is ready to listen, Fumio takes a deep breath.
"First of all. I owe you an apology." He starts.
"Apology? For what?" Sayuri asks.
"Is it because you've kept… your abilities from me?" While she feels a bit betrayed by Fumio keeping his ability secret, she feels that it is Fumio's right to do so.
