.hack//sign- Despair- Episode #21

After a talk between Bear, Mimiru and Subaru, it seems that Tsukasa is once again missing. Subaru of course blames herself, but Bear trys to make the most of it. Subaru says she should try looking in the place where he took her, but it'll be difficult, since she only got there via Tsukasa's guidance.
For a moment, we see Tsukasa. His eyes are glassy, the teddy bear is knocked over, and the trees are almost gone.
Another meeting of the Sora group is taking place, and it seems that both groups are stuck. Sora is once again making fun of how scatter-brained Silver Knight is. When Silver Knight tries to say he knows more, Sora says "Did you know Tsukasa is a girl?" Silver Knight was wide-eyed when he found that Tsukasa in the real world is actually a girl, not a guy as he looks like in The World.
B.T., obviously doing some spying, starts talking to Subaru. B.T. is about to tell Subaru the secret of Tsukasa's gender, but Subaru says she'd rather find out about Tsukasa from Tsukasa, not anyone else.
Crim is alone on a server, fighting a huge monster. It is large, a reddish colour, and seems like it has been torn apart, but it's still moving. Crim is struggling with this monster. Even though he's dealing direct damage to the monster, it's not killing it. Crim finally concludes that this is one of the monsters that cannot be defeated.
Crim reports back to Bear's group and tells them about the undefeatable monster, and the group tries to find out what's causing such irregularites.
Back in Tsukasa's ex-haven, Tsukasa is just sitting there, destroying the teddy bear. Maha appears, and Tsukasa gives him a weird twig.
After a couple moments of pondering the situation, Bear's group goes over some evidence and decides that they have two objectives: One, to find the girl and Two, to defeat the undefeatable monster.
Sora, who's idea it was to steal their conclusions, found out about the undefeatable monsters, and decides to go hunting around. He kills two players when they know nothing about them.
Bear remembers the broken man from the upside-down dungeon, and thinks it would be best to visit him again. But since they have no idea how to get back to that place, they are a bit stuck. Bear thinks it would be best to contact Helba. But to find her, Bear uses Mimiru's finding strategy: using the message boards.
Maha takes the twig and goes through a portal into a large green space. The girl is floating upside down, and the voice talks to Maha. It says Maha shouldn't worry about Tsukasa, because he isn't needed anymore.
Bear makes a remark about how his plan went, as he is now face-to-face with Helba.
