More details, including some new screenshots of Haseo and Ovan, have emerged from Weekly Famitsu about .hack//G.U. Last Recode's all-new 4th volume, making G.U., a bona-fide tetralogy!
In Vol.4 "The World R:2" Is Shutting Down And Time Is Running Out To Save Ovan
A year and 3 months have passed since Haseo last logged into The World R:2, after the events of Vol.3 Redemption have ended. CC Corporation has since announced to close down the MMORPG on 31 December 2018 due to having many server problems. Haseo had been trying to investigate the whereabouts of Ovan who disappeared into the depths of the network, and finally decided to log back into The World R:2 to find and rescue Ovan before the game shuts down, to be able to fulfill his final promise to him.Haseo's 5th Form
When Haseo comes back to The World R:2, he found Ovan encased in a giant ice stalactite inside a new Lost Ground named the Great Cave of Cua Holm, where the giant stalactite is located at the center of the cave while being surrounded by epitaph stones. Haseo tried to break the ice but was unsuccessful even with his current Xth form, so he gathers his old friends once again on an adventure to rescue Ovan.
Haseo will also gain a new power in Vol.4 that will give him another new form, called the 5th Form. Another new weapon, the whip-sword, is also added to his arsenal. The Famitsu article has also confirmed that Silabus, Gaspard, Atoli, Shino, Alkaid, and Tabby will return to reunite with Haseo and help him in rescuing Ovan.
