Happening Weather

Happening Weather is the one hundred and thirty-eighth chapter of To LOVE-Ru.

Plot
Yuu calls up Akiho asking if she wants to go out on Sunday, but she apologizes to him that she already had plans for that day.

Meanwhile, Yuu sees Riko being chased by Yami whom says she will not show mercy even if in the guise of his female counterpart.

One hour ago, Rito accidentally walked in on Mikan's room while Yami was trying on some clothes and caught her half naked. Rito then ran out of the room and Lala (which Saruyama asked to see Riko) accidentally zapped him with the Koro Koro Danjo-Kun turning Rito into his female counterpart, Riko.

Back to now, Riko loses Yami around a corner, but the Principal is there and says they meet before. Riko is worried and, indeed, the man moves in for a kiss. Just then, Yuu pulls Riko behind him and punches the Principal in the face. The man fly away and run scared.

Riko thanks Yuu referring to him as Yui's older brother. This causes Yuu to ask whether Riko is Yui's friend and notices that she looks like someone he knows (meaning Rito). Just then, the effect of the invention wears off and Riko comes back into Rito much to Yuu's disbelief.

Rito explains his story to Yuu and, even though it's unbelievable, he saw the transformation with his own eyes and ends up accepting it. Yuu now understand better her sister when she talk of Rito like a person who lacked common sense, but still don't get how she fell in love wih him. The two formally introduce themselves and Rito think that Yui' broher looked scary before, but instead is a good and openhearted guy.

Suddenly Yami comes up. Yuu ask if she's his friend and tells that Yami's attire is awesome, but Rito gets up telling him that she is dangerous. As usual, Rito trips and falls face first into Yami's chest. Yami then beats up both Rito and Yuu with her power. Yami then tells Rito that if she killed him her life on Earth would end and she tells him not to anger her. Stll on the ground, Yuu ask Rito if Yami is an alien also and Rito explain she's an assassin and he's her target. Yuu remarks that Rito has got it rough. Yuu tells Rito that at least his life isn't boring and that, if he ever needs to talk, he can come and see him.

Yami then notices that they still have some energy and the two run off.
