The Nepleslian Treaty of YE 32 (also called Yamatai-Nepleslia Alliance Treaty) was drafted by Hanako in YE 32 as a means of reestablishing relations between the Democratic Imperium of Nepleslia and the Yamatai Star Empire and to create an alliance to combat the Mishhuvurthyar. The current, revised version was signed by Empress Himiko I. However, Nepleslia's Senate failed to approve it due to an NMX attack on their Senate, which destabilized their government.

This treaty creates an alliance between the Democratic Imperium of Nepleslia and the Yamatai Star Empire.
