"A moonlit sea, the fading scent of summer, and a sky full of fireworks... the setting is absolute perfection. Romance is practically guaranteed to bloom!"
"Except for the massive crowd and the fact that we're surrounded by rivals."
"Well, it can’t be helped. As long as the 'strongest heroine' is around, I knew it would be impossible for us to get Yugo all to ourselves."
The girls spoke with a touch of wistful regret as they watched the brilliant blossoms of light burst one after another against the dark velvet of the night sky.
As the final night of their school trip arrived, they had entertained thoughts of whisking Yugo away to enjoy this perfect moment in private. However, once they realized just how many competitors they were up against, they were forced to abandon the plan.
Besides, none of them could envision a future where Yugo and the "strongest heroine"—his younger brother, Fee—were ever truly apart. Recognizing from the start that their romantic schemes were fundamentally flawed, they decided that being able to watch the display together as a group was more than enough.
"Hah! Even so, the fireworks of Wind Island are truly magnificent! They are every bit as grand as those we see back home in Yamato!"
"You're right. When I think about everything we've been through to get here, it feels even more special..."
While the girls shared their thoughts and admired the spectacle, Yugo gazed up at the sky alongside Fee and Yui.
A sense of nostalgia washed over Yugo as he watched the quintessential summer tradition—a sight he had seen many times in the world before his reincarnation. Echoing Setsuna’s words, he spoke softly.
"A lot really did happen... It was a long, hard battle. But seeing us all here together, watching the fireworks... I'm glad it turned out this way."
Even as he watched the shells launch and bloom, the overwhelming thought in his mind was simply how much they had endured. A crimson firework burst wide before him, a vivid reminder of a summer filled with memories that were intense, passionate, and often brutal.
"...It’s a little bit lonely, isn't it? Watching the fireworks makes me realize that summer is actually coming to an end."
"I know what you mean... Precisely because we finished everything safely, the end of the season feels even more bittersweet."
Beside Yugo, Fee and Yui watched the display with a trace of melancholy. They could feel the school trip drawing to its inevitable close.
Yui, who watched the fireworks through her Mind's Eye, seemed to sense the lingering aura of a conclusion. As she hummed in agreement with Fee’s somber voice, Anhel suddenly spoke up.
"Whoa there, you two! Just because the official show is wrapping up doesn't mean the night is over. Not by a long shot!"
"What do you mean?" they asked in unison, tilting their heads in confusion.
With a triumphant grin, Anhel reached into her cleavage to retrieve something. In response to her characteristically bold use of her Four-dimensional Cleavage, and before Yugo could even interject with a quip, she presented her prize to the group.
"Ta-da! Presenting the Fun Fireworks Set and Big Sister An’s Special Handmade Fireworks! I’ve even got the ignition Magic Item ready to go. Once the big show is over, we’re going to have ourselves a real party!"
"Wait, what!? When did you have time to prep something like that, Ann?"
"Let's just say I figured something like this might come in handy. A capable woman never neglects her preparations."
"That’s our Ann! But is it really okay? Won’t the teachers get mad at us?"
"Relax. I already cleared it with Professor Castle!"
"Seriously? He said yes?"
"Consider it a reward for helping solve the incident. He did give me a lecture about not getting too rowdy, not doing anything stupid, and making sure we don't stay out too late, so we’ll have to be on our best behavior."
As Anhel puffed out her chest with a proud huff, her companions broke into spontaneous applause.
Satisfied with the arrangement, Yugo took the fireworks set from her with a grin and looked at his friends.
"Alright! Then once the official display is done, we’re holding an after-party! We’ll use these and celebrate together!"
"Yes! That sounds wonderful!"
"The school trip and summer are ending soon... but they’re not over yet. Let's make the most of every second!"
"Exactly! Life's a waste if you aren't enjoying it to the max!"
Yui and Fee nodded vigorously, their faces lighting up with wide smiles.
Spreading his arms as if to embrace the night, Yugo’s eyes sparkled with a radiance that rivaled the light show above. In a voice filled with pride for the friends who had survived the summer's heat and the weight of battle alongside him, he shouted a declaration of the peace they had won.
"Case Complete! But... our summer isn't over yet!"
It was their final night on Wind Island. Together with his brother and his companions, Yugo created the best memory of all.
The memories of their fierce struggle and the joy of their school trip would remain etched in their hearts forever, never to fade.
While he never wanted to be caught in another incident like this one, he found himself hoping to spend the next summer—and the one after that—enjoying these same days with these same people.
With that thought in mind, the Hero who had finished his battle allowed himself to enjoy a single, brilliant page of a student's youth.
