Ryuju

An abomination created by Infel and Nenesha out of Frelia's trees by singing Sublimation. This monstrosity was made to challenge Croix and his party to a game in which they gambled the future of the world, although Cloche managed to destroy a large part of it with Replekia, leaving only a few of its tentacles and its core. The fight against it constitutes the first and second phases of Ar tonelico II: Melody of Metafalica's final battle.

First Phase
In this battle, during which EXEC_over.METHOD_SUBLIMATION/. ~lamenza plays in the background, the party will be fighting against Ryuju's tentacles, all of which are shaped after snake heads. There are a total of three tentacles, and after defeating one, the party will be put to fight against the next one without rest or a chance of recover, so it's a good idea to be prepared. The tentacles are resilient, but they aren't very strong, as the only attacks they all can use are Predation, which hits a party member once; and Universal Destruction, which hits all party members four times; although neither can cause large amounts of damage.

So the player only has to push through and continue fighting. Once all tentacles have been annihilated, the second phase to this battle will commence.

Second Phase
As soon as the final tentacle is destroyed, the music will change to EXEC_over.METHOD_SUBLIMATION/. ~ee wassa sos yehar, signaling that the second phase has begun. This time around, the player will be fighting against Ryuju's main body and a secondary tentacle. The tentacle itself is quite an annoyance, being able to use Evil Mist to hit all party members three times and also causing random status ailments every time it isn't blocked perfectly, but the main body is the true problem: aside of being very strong itself and capable of halving all elemental damage it receives due to its resistances, it also has access to the following attacks: Hellfire, which hits all party members three times; Breathe of Purity, which hits all party members four times; Thorns of Life; which complements the Evil Mist of the tentacle by hitting a party member twice and causing random status ailments; Victimize, which hits all party members twice; Melody of Origin ~Prelude~; which hits all party members five times; and finally, Melody of Origin ~Finale~, which hits all party members ten times.

Both versions of the Melody of Origin also have the particularity that they force the Reyvateils to release the Song Magic they are charging at the moment it gets used; so the player might have a Song Magic wasted if it didn't charge long enough when Ryuju uses any of these attacks. Therefore, it's advisable to finish the first phase of the battle by killing the last tentacle only with the vanguards and leave the Reyvateils charging their song in preparation for the fight with the main body. That way, if it uses the Melody of Origin, it will only trigger its own death.

As this is also the final battle, it's recommended that the player outfits their party on the best equipments they have at the moment and use all of the Dualithnode Crystals they have in Dualstalls in order to have them in the most optimum way possible. The same goes for the equipping of Girl Powers and Diving: at this point, two of the four Cosmospheres (the one of the Reyvateil chosen and the secret one made available right before this point) should have been completed, allowing the Reyvateils to gain the strongest Song Magic they can use in the game.
