My Daughter Left the Nest and Returned an S-Rank Adventurer

As time passed and Angeline grew up, she decided to become an adventurer and set out for the guild in the capital. She soon made a name for herself as the "Black-haired Valkyrie", thriving as an S-rank adventurer. For the first time in a while, Angeline decides to take a long break, and is looking forward to reuniting with her father Belgrieve after five years.

On Belgrieve's farm, Sasha, Bordeaux family's second daughter, visits to thank Angeline for rescuing their sister, Seren, from robbers. Giving Belgrieve gold coins, Sasha asks to learn swordplay from him. Elsewhere in Orfen, Angeline handles a magical beast problem, meeting a past merchant employer who shares tales of her father.

In Orphen, retired former S-rank adventurers Chebolg and Doltos arrive. Concerned about a massive outbreak of magical beasts, they decide to return to action to confront the root cause. Joining forces with Dragon Slayer Maria, another former S-rank adventurer, Angeline and her companions head to the source, an abandoned dungeon and combat the menacing monsters.

Angeline finally returns to her hometown Tornella and reunites with her father, Belgrieve. She spends peaceful days with him, accompanied by Anessa and Miriam. Belgrieve is familiar with Angeline’s old habits and easily defeats her during a sword sparring session. Recognizing the dangers she might face as an S-rank adventurer, Belgrieve challenges her again to test her resolve.

Bordeaux faces an undead invasion, leading Angeline's adventurers to fight fiercely. Amidst the chaos, Angeline confronts a shadowy figure akin to a previously defeated demon lord, adding a dramatic twist to the siege.

Charlotte and Byak, along with Count Marta, plot to assassinate the Bordeaux family’s eldest daughter, Helvetika. In response, Sasha, the second daughter, rides alone to apprehend Count Marta. She encounters Charlotte and Byak, plotting the attack. In a struggle in the dark, Sasha faces a desperate situation.

After resolving the Bordeaux assault, Angeline returns to Orphen, and Belgrieve heads back to his hometown, Tornela. Back home, Anegeline eagerly starts searching for a bride for her father to prevent his loneliness, approaching ex-high rank female adventurers and orphanage sisters. Meanwhile, in Tornela, Belgrieve encounters an elderly elf named Graham.
