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.)
Despite how she looks, she's 
far older than the rest of us.
بالرُّغمِ ممّا يُوحي به مظهرها، إلّا
أنّها أكبر بكثير من بقيّتنا
Anders als man vermuten könnte,
ist sie viel älter als wir.
Aunque luzca así,
tiene más años que nosotros.
Aunque tenga esa pinta,
tiene más años que nosotros.
On ne dirait pas,
mais elle est bien plus âgée que nous.
Per quanto non lo dimostri, 
è molto più vecchia di noi.
Apesar de não parecer, 
ela é mais velha que nós.
Она выглядит молодо, но на самом
деле она гораздо старше нас.
