In the Name of Revenge... is the sixty-third chapter of To LOVE-Ru.
Plot[]
At school, Lala clings to Rito, and Ren comes running up, telling Rito not to force Lala. The boys beat each other until Lala tells Ren to stop fighting with Rito, which makes him sad as he runs off.
While on the roof, Ren wonders why Lala only likes Rito. Ren then sneezes, turning him into Run. Run doesn't understand how Ren could hate her beloved Rito and thinks the one who's getting in the way is Lala. Run then recalls Lala's treatment of her when they were younger. Once Lala sprayed Run with a super powerful water gun, took her to the tallest point on Deviluke (Run is afraid of heights), and caught a giant sea monster. Run then decides to kill two birds with one stone: which will make Lala look really stupid in front of Rito, so he will leave her as Run will get to pay Lala back for her childhood.
At lunchtime, while Lala and Rito are eating lunch together, Run comes up and says that they should eat lunch together like they used to. She tries to prank Lala by giving her a super spicy sandwich. Lala eats it and says it's a bit spicy, as she isn't really affected by it. Rito then decides to try one of the sandwiches, but it's ridiculously hot to him who runs off screaming and searches for water. Lala isn't phased while Run says sorry to Rito and knows what kind of tongue Lala has.
Later, Lala helps Haruna carry some books, and Run tries to use a clothes-removing gas grenade (made from Gama-Tan's oil) to embarrass Lala in front of the school. But as she's about to throw it, Rito asks her what she is doing. This shocks Run, causing her to drop the grenade that destroys their dress. Lala and Haruna turn to the corner, and they see Rito and Run naked, which causes a scared Haruna to slap him.
As a last-ditch effort, after school ends, Run tries to use a giant hammer to hit Lala, claiming her fault that she is one end embarrassed in front of Rito. As she is running in, Rito comes up to talk to Lala about his terrible day. Knowing that she can't stop herself and Rito will be involved again, Run decides to sneeze to frame Ren. Ren then hits Rito, and Lala yells at him for it. Ren tries to explain that it's not his fault while Rito asks why this happened.
