I'm not sure specifically about the content of 'Konosuba Visual Novel' in s2 ep6 as I haven't fully explored it. But generally, the Konosuba series is known for its comical and satirical take on the isekai genre. It might feature the wacky adventures of Kazuma and his party in this particular episode of the visual novel.
Well, identifying where Konosuba Season 3 is in the novels can be tricky. It depends on various factors like the story progression and the author's narrative choices. Sometimes, elements from multiple parts of the novels could contribute to the season's plot.
The end of Konosuba Season 2 in the light novel shows the characters growing in their own ways. Megumin becomes more proficient in her explosion magic, albeit still with her comical over - the - top love for it. Darkness continues to be... well, Darkness, with her strange masochistic tendencies. And Kazuma is still trying to make the best (or worst, depending on how you look at it) of his situation in this strange world.
The story progresses with more comical and adventurous elements. Kazuma's schemes to get rich quick or gain some sort of advantage usually backfire in hilarious ways. The party also meets new allies and foes. New areas of the fantasy world are explored, bringing with them new types of quests and challenges.
Celebrating Years Season 2, episode 13 was the 13th episode of Celebrating Years Season 2. The play told the story of a young man with a mysterious background, Fan Xian. He had experienced the trials and tempering of his family, the martial world, and the court. He upheld justice and kindness and began a new journey in life. In this episode, the news of Fan Xian using the name of investigating corruption to target the Second Prince's faction spread like wildfire in the Jingdou officialdom. At the same time, the murderer of Baoyue Brothel was finally caught. The battle between Fan Xian and the Second Prince was becoming increasingly white-hot. Baoyue Brothel became a tool for the Second Prince to check and balance Fan Xian. The Second Prince tried to pull Fan Xian into the water and cause the people to boil. Fan Xian walked the path of being close to the people. What he valued more was the will of the people. Fan Xian asked his subordinate Deng Zi Yue to spread the word that the manager of Baoyue Brothel was Yuan Meng, and Yuan Meng was an old lover of the Second Prince's subordinate, Li Hongcheng. This was the reason why the Second Prince was framing Fan Xian. Fan Xian and the Second Prince displayed two countermeasures. Fan Xian walked the path of being close to the people. What he valued more was the will of the people. Therefore, Fan Xian asked Deng Zi Yue to spread the word that the manager of Baoyue Brothel was Yuan Meng, and Yuan Meng was an old lover of the Second Prince's subordinate, Li Hongcheng. Anyone with a brain would think that the Second Prince was framing Fan Xian. As for the details of the specific plot, one had to watch the 13th episode of the drama to understand.
