ok why are you guys even questioning a typo? look at the listed "linked" quest that it's part of... yes their are two with almost the same name... this page is a post of the wrong one... look at spelling difference of 1 letter... and if u review quest and look at other weapon, other weap has an image to verify, and the quest only lists 1 of these... so who ever is mod'n this board needs to delete this page imo...
The typo isn't the name, but the effect rather. One is a relic weapon, that lets you use Tachi: Kaiten only in Dynamis. After completing some quest or something like that, you upgrade to the relic weapon, that can be used anywhere.
ok am i looking at this correctly? theres two GKs that do exactly the same thing? the Totsukanotsurugi and the Tosukanotsurugi... fill in the blanks i dont know much about relics
