The Waves come to that world, and... Everyone has to fight. Naofumi's in charge, of course.
However... L'Arc shows up.
"Kiddo? There you are!"
"L'Arc?"
After the Wave... L'Arc ends up stuck here with Naofumi, who facepalms.
Naofumi then avoids all contact with L'Arc...which only gets L'Arc to chase after him harder, searching for him.
He hides with Seiya, who asks him, "Why are you avoiding him?"
Naofumi's unusually anxious, "He throws me off... He's the only one who can do that."
"So it's like that?" Seiya blinks.
"He also tried to kill me before…" Naofumi sighs, "I don't know if we can still be...friends after that."
Seiya nods, "I see... Then you can hide with me for now."
Naofumi smiles, "Thanks."
When L'Arc finally catches up to him, cornering him, Naofumi instinctively uses Shield Prison on himself as there's nowhere to run anymore.
L'Arc taps the shields, "Kiddo? Can you come out? We need to talk."
"No way!"
"Oh, C'mon~, Kiddo? Please?"
"Go away L'Arc!"
L'Arc smiles, "That's it."
He uses his scythe to pry open the ball of shields before jumping inside, Naofumi yelping. The ball closing once again.
After the skill timed out, Naofumi sighs in defeat as L'Arc has gotten a hold of him. Happy, L'Arc picks up Naofumi easily before running away somewhere to talk in private.
As for Naofumi and Seiya's relationship... They get along quite well. Seiya asks to test his strength against Naofumi's shield, who eagerly agrees.
Also... Seiya lifts Naofumi easily. Much to Naofumi's embarrassment...
Then... L'Arc drags Naofumi somewhere by the hand, calling it a "date," which gets Naofumi flustered.
