I think the story in SMT IV is good. It has a depth to it that makes you think. The world-building and the way the narrative unfolds are both impressive.
One idea could be to have characters from different universes within the 'devil survivor 2' world meet and form unexpected alliances. For example, a group of normally opposing demon summoners having to work together to face a greater threat that endangers all of their worlds.
Pairing a tech - savvy character from 'devil survivor 2' with a magic - using character from another world could be really interesting. The tech character could be fascinated by the magic, and the magic user could be intrigued by the advanced technology in the 'devil survivor 2' world. They could combine their skills in unexpected ways to face challenges, like using technology to enhance the magic or using magic to power up technological devices.
The OST lineup of " Celebrating the Second Season " included Li Jian, Zhou Shen, Liang Long, Liu Duanduan, Zhang Haowei, and Guo Zifan. They sang songs such as "In My Lifetime,""Excuse Me," and "Aiya." These songs were meant to continue the story of " Celebrating Years " with a melody and bring a new chapter to the audience. " The Second Season of Celebrating the Year " was an ancient drama adapted from Maoni's novel of the same name. It was starred by Zhang Ruoyun, Li Qin, and many other stars. The second season started filming on November 3, 2022, and was announced to be completed on October 17, 2023. It was aired on CCTV-8's primetime slot on May 16, 2024.
For me, Persona 5 takes the cake for the best story in the SMT series. It has a compelling narrative with well-developed characters and a unique theme.
