A sword based on older technology. Sharp enough to slash enemies apart, even without the aid of photons.
- No longer drops - replaced in drop tables by Last Survivor-NT.
*A returning weapon from Phantasy Star Online, where its special attack drained enemy HP to heal the user. Reappeared in the Japanese PC version of Phantasy Star Universe as Last Survivor Replica, while the Last Survivor name was given to unrelated Twin Daggers. Its potential may be a reference to its descriptions in both games, which describe it as "said to protect the life of its wielder in any battle".
- When upgraded to +10, awards the title That Which Remains.
