Izayoi Sakamaki and Rias Gremory arrived at the firework festival, their eyes filled with anticipation for their first date.

They walked hand-in-hand, exploring the myriad of stalls. Rias' face lit up at the sight of a cotton candy vendor.

They found a quiet spot by the riverside, away from the crowd. Rias admired the view, while Izayoi looked at her, admiring her beauty.

They chatted and laughed, enjoying each other's company. The fireworks began, illuminating the sky and their faces with a multitude of colors.

Suddenly, a rogue firework veered off course, heading straight for the crowd. Izayoi, noticing the danger, quickly pulled Rias away.

The firework exploded harmlessly in the river, but the incident left Rias shaken. Izayoi held her close, promising to protect her.

Rias thanked Izayoi, her eyes reflecting gratitude and a newfound respect. Their bond deepened, giving their date a special significance.

They returned to the festival, enjoying the games and food stalls. Despite the earlier incident, the night was filled with laughter and joy.

As the festival ended, Izayoi and Rias stood by the riverside, watching the final fireworks. Rias rested her head on Izayoi's shoulder, a content smile on her face.

Izayoi wrapped his arms around her, a soft smile playing on his lips. Despite the earlier hiccup, their first date had been perfect.

On their way home, they walked in comfortable silence, their hands intertwined. The night was drawing to a close, but their story was just beginning.

As they reached Rias' home, Izayoi gently kissed her hand, promising her another beautiful date. The night ended with their hearts fluttering in anticipation of what lay ahead.
