The next day, Tsukasa found herself in her room. 'It must be Gio-nii.' She thought. She smiled. She got ready and went out of her room. She went to the training room. And watch the guardians fight among themselves for a while and she think that compared to the past them, they're pretty weak. They're so predictable and they have one of the characteristics she hates the most. They just attack, some thinking and some not, and it seems like they don't care whether they die. 'Didn't you promise me to take care of yourselves a little more? Do you think that not caring whether you all die while fighting and not taking care of yourselves is a good thing? If you all think that's great and you're all protecting the people you love, then there must be something wrong with your heads. Saying 'it's alright to die as long as the person you love is alright' is so selfish. That's just being coward, being scared to feel the pain of losing someone important. Physical wounds can heal in a matter of time but the wounds that you will all cause to the people that care for you will remain and scar to their hearts forever.' Tsukasa thought bitterly. After some time, Tsukasa went out of her hiding place. The guardians all stopped what they were doing and looked at her.

"What do you think of their fighting style?" Reborn asked. Reborn knew that Tsukasa was watching since the start.

"I don't have any comment in their fighting style but when it comes to strength, they're pretty weak." Tsukasa said. She saw all the guardians glared at her.

"If you really think were weak, why don't you fight us? You can't even fight and you're acting like you're so great." Gokudera said bitterly.

"… Then, I'll fight all of you. I will fight all of you the same time." Tsukasa told them.

The guardians started attacking. She watched them carefully and did nothing but defend. She didn't attack them. 'They're at their reckless but readable moves again. If I'm a real enemy, they could have died any second. There are many places where I can attack. I really hate them.' Tsukasa thought. She started attacking them and within half a minute, the guardians were all on the floor. They can't move even an inch while Tsukasa haven't even started sweating. "You're all selfish. You're the type I hate the most. Thinking "It's alright to die as long as I protect the important people to me" is just so selfish. You're all just cowards. You're all scared to feel how to lose somebody. You think you're great if you can die protecting the one you love but the truth is what the person you think you are protecting will suffer more than you all suffer and you're the one who cause it. Physical pain can heal but the pain you let them feel in their hearts will never heal. It will scar. Besides, if you all die, who will protect the one you love? Think about that before throwing your lives away." Tsukasa told them. No one in the guardians dared to say a word to justify them because they know that Tsukasa is right. "Yamamoto it's time for your test." Yamamoto stood up. He started attacking Tsukasa and when Tsukasa let her guard down, he kicked her. Tsukasa looked at Yamamoto and then at Reborn. Reborn was frowning. Tsukasa smiled. 'Reborn knew what this test was about.' Tsukasa thought.

"You failed, Yamamoto." Reborn said. The guardians were shocked. Yamamoto managed to land a hit on Tsukasa but still failed.

Tsukasa stood up. "Wait, Reborn. Give him another chance." Tsukasa said looking at Reborn and then, she looked at Yamamoto. "Think about why you failed carefully. I'll just give you another chance. If you failed that one, you really failed." Tsukasa said seriously. Tsukasa went out. When she was already far away, she saw Uri, Natsu, Hibird, and the other animals. She smiled at them. She quickly took a first aid kit. "Natsu, please deliver this to the guardians with the others. I know they won't bother to go to tend their wounds if they someone do not give them this. I can't give this myself because they won't accept it. They hate me now. One more thing, I know you remember everything. Please help them pass the test. Make them understand what they are lacking or what they need to learn in order to be themselves, in order for them to be strong again. I don't want them to be hurt. Please, everyone. Yamamoto really changed. That's not the carefree and always happy Yamamoto. I know being in a mafia change you a lot but he should remember the real him. It will make him stronger." Tsukasa said. The guardians are listening to Tsukasa. She can feel many presences so and she doesn't focus so she doesn't know. She suddenly stood up. She felt a strong presence coming towards their location and she knew that it's not someone from here. She's not checking the presence near her but far. It's much harder to do that because it needs a lot of concentration. The guardians thought she found out that they are listening. They got ready to explain but were relief when she was walking towards a different direction. "Go find the guardians and give that to them after that go back inside the box. There are enemies nearby. I will take care of the others that might cause great damage and leave the weak one to the guardians. Hurry." Tsukasa ordered and run towards the enemies with great speed. The guardians followed Tsukasa. Tsukasa easily beat the first set of assassins that attacked her. She may be even powerful than them so they wondered why she let her guard down when she was fighting Yamamoto. When many assassins attacked her, she didn't have any problem fighting. She's just fighting with bare hands and not killing her enemy. She's just putting them to sleep. An assassin tried to kill her. The assassin was all beat up and can't move for a moment but instead of killing him or beating him up like what Yamamoto did, she stopped and let the enemy rest for a second.

"Why? Why aren't you attacking" The assassin asked. The assassin looked at her cautiously. He didn't even dare to blink like if he did, he's going to get killed. He looked at Tsukasa as if calculating her every move. Tsuna smiled which caused the assassin to blush since she looked cute with that sincere smile of hers.

"Isn't it obvious?" Tsukasa asked with an innocent voice while still smiling. "It's not fair to attack someone who is not in the condition to fight. Even if I did beat you, if you just let your guard down or not in the best condition, victory will be useless. It doesn't matter if you're an assassin, enemy or whatever you are. What's important is I got to fight someone in their fullest while giving everything I can because if I hold back, it will be disrespectful. If I attack you, I will be the same as killers and assassins that sunk low. I will never us dirty tricks because as long as I have something to protect, I know that I will never lose." She explained. Then it struck Yamamoto like an arrow. She's right. Even though she doesn't act like it but all she's doing is what's good for all of them. After the assassin recovered, they started fighting but of course Tsukasa won easily. The next, day Yamamoto passed the test.

"Thank you" Yamamoto said with a cheerful smile. She smiled back. Yamamoto blushed but Tsukasa didn't notice it. Yamamoto is finally being himself. He's beginning to revert back to his cheerful, sport, oblivious and kind self.
