Tsunami-no-ki

Tsunami-no-ki (lit. "Tsunami tree" in Japanese) is the oldest standard Juraian Royal Tree in existence and the core power source of Tsunami-fune.

History
Long ago, the Chousin Tsunami created Tsunami-no-ki as the first standard Royal Tree on Jurai as part of her promise to protect the descendants of Rayleigh Glory and Masaki Raregroove. Essentially, Tsunami created Tsunami-no-ki to serve as a conduit for her power so that Juraian royalty could use it to benefit Jurai; for this reason, Tsunami-no-ki could even be considered to be another version of Tsunami herself. Over the eons that followed, Tsunami-no-ki released seeds that created more Royal Trees, which became known as "first-generation" trees to the Juraian people. Eventually, Tsunami-no-ki became the core of Tsunami-fune, one of the first Juraian treeships.

In 150,081 CMT, Yume explained to Hishima and Takashima that she could not have immediately suppressed the sentience of Bizen without Tsunami-no-ki sensing that one of her offspring had died, so Yume instead had to merge with Bizen and use her own will to keep Tsunami-no-ki from realizing that Bizen had become dormant.
