Smile Baby ~Baby Panic~

Smile Baby ~Baby Panic~ is the fifty-first chapter of the To Love-Ru Darkness manga series.

Summary
On her way home from school, Yui sees a couple going for a walk with their baby, whom she smiles at, causing her to imagine what it would be like if she and Rito were to have children.

Meanwhile, Rito finishes up helping his father at work, and he begins to head home. However, he is stopped by Nemesis, and is surprised she's still in the city. She begins playfully flirting with him, telling him that now Mea has parted ways with her, he's her "one and only beloved servant". She begins to pull him closer to him seductively until suddenly, spraying him with a mysterious gas. She reveals that the gas is gigantification gas, which she acquired from a smuggling organization she had destroyed for fun the other day. She explains the gas was developed from a certain kingdom and used as a biological weapon during the Galactic War, turning anyone who came into contact with it into a giant until it was dealt with by the forces of Deviluke. Wanting to see its effects on Rito, she activates the power of the gas, ordering him to show her the legendary powers of giants.

However, after the transformation, Rito is turned into a mere baby, laying naked in his now over-sized school clothes. Nemesis makes a conclusion that the gas has a different effect on earthlings' constitution. Disappointed in not to see Rito in panic over getting gigantified and not wanting to be stuck with babysitting him, she notices Yui walking by and gets an idea.

Yui looks at her phone, and finds out her parents are out at a drinking party and Yuu is out with friends, and thus will be by herself for the rest of the day. Nemesis then comes up to her, disguised like a random schoolgirl, and hands a baby Rito (now dressed in a pair of footsie pajamas) over to her, asking her to "help someone in need". Yui asks if they've met before, but Nemesis tells her not to worry and to do her best with him before she runs off. Confused, Yui tries to understand what's happened.

Yui then holds Rito to her face and stares at him, thinking that he looks familiar. Her serious expression causes him to start crying, attracting the attention of Ageru Matome. He asks her what she's doing with a baby, and asks her if he's hers despite her not being out of high school yet. Speaking a loud voice, Ageru comments how Yui seemed too sexy for a moral committee member, and he now understands was the charm of a young mother. Some people nearby overhears this and looks at Yui beginning to judge her and someone recognize her like the daughter of the lawyer Kotegawa. Totally embarassed for the misunderstanding, Yui then is forced to run off with Rito sobbing in her arms. She then comes across Mikan, who asks her why she's holding a baby, and begs her to help stop his crying.

At the market, Momo is thinking to herself about her mother now knows about the Harem Plan (from previous chapter), and what it could mean for her personal relationship with Rito. Suddenly, Nemesis shows up, no longer in disguise, and greets Momo, who angrily asks her if she's plotting again. Nemesis responds by tossing her Rito's school bag filled with his clothes and says he is now in the care of Yui. But Momo assumes it means Nemesis has placed Rito in sadomasochistic danger, and runs off to find and help him. Nemesis notes how defensive of Rito she is, and walks off to eat some more dango.

At the Yuuki household, Mikan is cradling the now happy Rito in her arms, deeming him "cute" while Yui mopes in the corner. They discuss how 'some stranger' just dropped him off on them, and how they'll be able to get him home, not realizing who he really is. Mikan points out that, since the person knew Yui's name, she'll most likely be back in a while to pick him up. Yui agrees, and compliments Mikan on how good she is with handling the baby. Mikan responds by saying she and the baby seem to be "on the same wavelength", and how much better Rito would be with him, since he took care of her when she was a baby and since he's had great experience with raising Celine.

Rito then lifts Mikan's skirt up and begins crawling around inside. Yui tugs him out, lifting him up and firmly stating she wants a turn playing with the baby. Rito begins crying again while Yui tries to tell him to play with her. She then lifts him into the air in an attempt to play with him, but Rito then pees on her, soaking Yui's shirt. Yui notes he wasn't wearing a diaper, so Mikan decides to go out and buy some while Yui will take a shower with the kid. After taking his footsie pajamas off, Mikan looks him over and determines "it's a boy". This causes her to reflect on when Rito used to help change her, making her embarrassed as she leaves to get the diapers.

In the shower, Rito happily plays with a soap dispenser, pressing down on the nozzle and cooing. Yui becomes annoyed when the soap keeps hitting her, and responds by forcibly taking the object away from him. Rito breaks into tears yet again, so Yui panics and tries to calm him down. Rito dries his eyes and notices her bare breasts, and smiles as he reaches out to touch one. He grabs one of her nipples, making it harden, and begins to suck on it due to his new infant tendencies despite Yui telling him she doesn't have anything coming out yet. Rito continues 'nursing', while Yui is overcome with a strange feeling. She lowers her defenses, cradles him in her arms as she lets him enjoy the experience, and identifies her feeling as happiness.

A while later, Rito is clothed and happily hugging Yui's leg and playing with her left breast, while Mikan watches in amazement at their new bond. She asks if the skin-on-skin relationship is really as important as it's made out to be, and Yui embarrassingly admits to it. Momo then comes in, asking if Rito's okay, while Mikan and Yui have no idea what she's talking about. Just then, the gas wears off and Rito is turned back to normal with his normal body (now stark naked). Mikan and Yui stare directly at Rito’s penis, trying to process what just happened, while Rito asks what just happened and where he is. A surprised Mikan asks him why he was a baby. Rito doesn't undestand what she means and suddenly notices his nudity asking where his clothes went and a horrified Yui calls him "shameless" before slapping him.

Later on, Nana, Lala, and Celine come back with Giga Boar's babies that were just born in the Cyber Safari, where they had just helped the mother give birth. Nana asks why Rito's cheek is swollen, and he responds by confusedly and indifferently saying that stuff happened while Momo sympathizes with him in her thoughts.

Meanwhile, Nemesis sits on a rooftop eating dango and hanging out with cats, declaring that Sainan is the perfect town for her to have fun in. At Kotegawa's house, Yui grumpily lays under her bed covers as usual, mortified, while her mom tries to call her down for dinner.

Trvia

 * It's the first time that Nemesis' schoolgirl disguise is used.
 * When Nemesis appears, a cat who look like Shironeko cover between her legs (because she usually don't wear panties).
 * Its first time that Matome Ageru, who normally is emotionless due of his weird face, show some emotional expressions.
 * A substance who can turn people in giant and used them as weapon could be a reference to the famous manga and anime Attack on Titan.
