Trouble Quest Final

Trouble Quest Final is the ninety-eighth chapter of To LOVE-Ru.

Summary
Lala's sisters, the 2nd princess Nana and the 3nd princess Momo, introduce themselves to everyone. Rito says is the first time he heard about Lala having sisters and is suprised she never talked about them.

Lala then asks them why they put them all through this simulation. nan explain they wanted to see those earthlings close to her and how they act under such circumstances to understand their personalities. Momo says that now know that her big sister has many good friends and ask to continue to look after her.

It turns out that Lala created most of the game a while back (Peke remember to Lala hat she started it shortly after they come to Earth and she take intrest in earthling games), but she had trouble with it and stopped working on. Nana and Momo finished it. Nana then tries to take all credit away from Momo (who actually worked on the program and had the idea to use Magical Kyouko as character in game), who puts her in a choke-hold with an angry face and says Nana just delivered the invitations. Lala breaks the fight up and demands they take them back to the real world. Lala ask sorry to all for the trouble caused from her sisters, but Haruna and Mikan says she don't have to apologize and our lives were not in danger. Meanwhile Momo demand Nana to use the remote controller and Nana comment about her sister fake smile. While trying to bring them all back to the real world the remote stops working.

Suddenly the world starts to collapse and Haruna saves Rito from a piece of falling rock. Lala understand that this is happening due to a system error caused by incomplete programming and Peke is worried because they at this rate everyone will be trapped in this dimension. Sunndely Rito blush because Lala dress is disappearing. Indeed all of their clothes start to disappear because they are made from data too. Rito inadvertently exposes himself to Yui and Yami when his pants disappear; Yui is shocked while Yami threatens to slice "it" because of her hate for all ecchi things.

Peke then transforms into Lala's dress and she goes to the supercomputer to try. Lala then fixes the bug rather quickly while the sisters says she is really he queen of the invention in their family. Lala saya thet in 30 seconds everybody will be transported back to the real world. Momo and Nana apologize and explain they wanted know more about Rito and if he can really make her happy. Lala says that they don't need to worry because she will never regret her choice in Rito.

Back in the real world, Lala watches Magical Kyouko show despite what happened in the game. Mikan tells Rito that Nana and Momo have gone back to Deviluke. Rito wonders if telling Lala that he may like her was the right choice.

Meanwhile, in the Amazon, the Principal is attacked by a crocodile while Run, Saki, Rin and Aya run wondering why, despite to be returned in real world, they are there.
