Ep 16. New Strength

Kazuki and Tokiko are finally back home after the events at the beach. While Kazuki is enjoying his time with his family, Tokiko spends her time with her own family. However, they both can't help but think about what's to come next. The battle is far from over, and they both need to get stronger if they want to defeat the Homunculi for good.

Meanwhile, Papillon is still alive and well, but he has a new goal in mind. He wants to test his strength against Kazuki, and he's willing to do anything to make that happen. He starts by stalking Kazuki, watching his every move from the shadows. He knows that Kazuki has grown stronger since their last encounter, and he wants to see just how much stronger he's become.

While Papillon is lurking in the shadows, Kazuki and Tokiko are trying to find a way to increase their strength. They decide to pay a visit to Dr. Butterfly, hoping that he might have a way to help them. Dr. Butterfly tells them about a special training ground called the L.X.E. Headquarters. It's a place where warriors from all over the world come to train and hone their skills. He warns them that it's a dangerous place, but they're willing to take the risk if it means getting stronger.

Kazuki and Tokiko make their way to the L.X.E. Headquarters, where they are immediately greeted by a hostile group of warriors. They quickly realize that this place isn't going to be easy, but they're determined to push through. They start training with the other warriors, learning new techniques and strategies to improve their skills.

As they train, they encounter many obstacles and challenges. They have to face off against powerful opponents that test their strength and abilities. Even with all the difficulties, they keep pushing themselves harder and harder, determined to become stronger.

Meanwhile, Papillon is still on their trail. He's been watching them closely, waiting for the perfect opportunity to strike. When he sees Kazuki and Tokiko entering the L.X.E. Headquarters, he knows that this is his chance. He sneaks into the training facility, looking for a way to corner Kazuki.

As Kazuki and Tokiko continue their training, they notice that someone is watching them. They soon realize that it's Papillon, and they know that they're in trouble. They try to flee, but it's too late. Papillon quickly catches up to them, and the battle begins.

The battle between Kazuki and Papillon is intense. Both warriors use all their strength and abilities to try and gain the upper hand. Kazuki's Buso Renkin allows him to keep up with Papillon's speed, but Papillon's strength is too much for Kazuki to handle.

Just when it seems like Kazuki is about to be defeated, Tokiko steps in to help. Together, they manage to gain the upper hand and defeat Papillon. As Papillon disappears in a cloud of smoke, Kazuki and Tokiko realize just how much stronger they've become.

With their new strength, Kazuki and Tokiko are ready to face any challenge that comes their way. They leave the L.X.E. Headquarters, ready to continue their journey and defeat the Homunculi once and for all.
