After returning from the Kingdom of Mismede, Touya and the others enjoy their daily life. Yet behind the scenes the women battle over the bicycle Touya created! Notice it, Touya!
At Sushie's request they head to Mismede and return to find Leen and Paula.
According to them, the crystal beast Touya and the others once defeated had appeared in Mismede as well, and Leen struggled to defeat it. So she began to take interest in Touya after he defeated the beast.
Acutely interested in the high spec Touya, Leen asks Touya and the others to investigate some ancient ruins, leading to the start of a new adventure! (Made easier with Gate.)
