Dakara Boku wa, H ga Dekinai - ep07

In the change of location from the human world to Grimworld, many things have change in the story. The first thing is the importance of Tuleslay, which is a key building important in the continue survival of Grimworld. The reason is that it maintains the Sun as well as managing all the energy that is collected from the human world. Also it appears to control how large or small the portal linking Grimworld to the human world is. Another important factor is that for a long time it was controlled by the Restall clan but recently the Garuda-Burogu clan has rebelled. This has ultimately lead to a switch of control of Tuleslay, however the deeper reason for this rebellion is unclear. It might be that the Garuda-Burogu clan doesn't like the idea of sharing or they might just not agree with how Tuleslay is used.

Once they are truly in Grimworld, Lisara wants to make a plan. However this proves to be meaningless since Ryousuke charge towards Tuleslay thoughtlessly. Which results in them being over run by the type of monsters they have been fighting. This ends with Kyuuru having to protect Ryousuke when he is left defenseless, but they are saved by Iria and this allows for them to retreat. Things become much worse once Ryousuke wakes up in Lisara home finding he is unable to summon Graham. Which means that if he tries to rescue Mina, he will only be giving the enemy Graham and that is the last thing that they want.

Later through Iria we learn that Merlot and Garuda-Burogu have teamed up, and Iria is currently has orders to invade Lisara's group and lead her it a trap. It seems like she is going to play her role as the pawn, but will she just let Lisara die. This become more clear when Iria tells Lisara about how she knows of a secret way into Tuleslay. That means that since Lisara is basically going to be traveling with a spy, at then end of the next episode we will see why Iria's loyalties lye. Then while this is going on Ryousuke is trying to gain back the use of Graham, however the question remains why did he lose the ability in the first place. Is because he use it too much, or is because that he is in Grimworld that his Shinigami half is now awakening.
