Like you said, the first theme song (Chihiro Yonekura-Lan-Zhong-Hui-Hui-Hui-Hui-Hui-Hui-Hui-Hui-Hui) and the second one. It sounds like a style

■ Pianyi のィカロス

Performer: Yuan 🀪 I like this song very much, but because I only collect 32K high-quality songs, and this song can't be found anywhere, I don't have this song in my MP3, but I still remember it all the time! An OP from Game King (I forgot the exact number)

All right, that's it. My hands are sore. I hope you will like these LZs I recommended. If you like more intense songs, KOTOKO is recommended, and if necessary, you can ask me for 32K high-quality songs. So, have fun.
