Important things that happened

Though Orion is both the name of the character and his constellations, their pronunciations are slightly different in Japanese (But both translate to Orion either way). The constellation is O-ri-o-n (オリオン) while the character is O-ra-i-o-n (オライオン).
Continuity - Orion and Lucky lose the Tomo KyuuTama to the Death Worm. Which is why it's found in the Death Worm later in the present day. Orion blames Lucky for losing it, but Lucky assures that he'll get it back.
