Next morning, biology lab. The students are getting themselves prepared for the experiments that morning, every group has at least three live frogs on their table, which is two people sharing one frog... Well, almost every group. Chris leered at Sky with a slightly annoyed look. "Well, I guess this experiment is considered as "not important" for you." "Chris..." Sky look at him with a "help me" look. "Don"t look at me, I"m not the one pairing with you, and I believe Kenji would come in with empty hands too." "Itsuki kun..." Sky switches his target to Itsuki and Itsuki turned his face avoiding eye contact with him. "Professor Stevenson, why are you doing this to me?" "Haha..."

So during the previous biology cla.s.s, Professor Stevenson is giving a brief explanation of a frog dissection experiment. "You will be doing this experiment in pairs, you can choose your own partner... Except for Sky, you pair with Seito Kenji, I can almost imagine Mr. Chris did the whole experiment by himself if he is to pair with any of you two, so Mr. Chris will be paired with Mr. Enomoto. Miss Ai, since you are alone, you can join any of the two pairs but I suggest you join Mr. Chris. Alright, during the next cla.s.s, you will need to prepare a living frog, for every pair. You can either buy from the pet shop or catch it from the drain when no one noticed. That"s all for today, dismiss. "

*Professor added a Mr or Miss in front of people"s names to shows respect, as for Sky and Seito... You can imagine it by yourself.

Back to the present. As expected Seito walks into the lab with empty hands as if nothing happens. However they didn"t pay much attention to him, they are all looking at that weird gigantic creature on Ai"s hands. "Ai... That"s a toad right?" Itsuki asks. "It is?" Ai looks slightly confused. "Most importantly where did you even get that?" He asked again. "The drain?" Ai answered with a slightly innocent tone. "Ah... I see.".

Chris look at the toad and look at Sky and Seito, he wonders what would happen if Ai actually joined them, then Sky noticed Chris"s eyes and seems to be misunderstanding something, he stood up and walks to Ai and took her toad. Chris stared at Sky with an unbelievable look, he never thought someone could be this dumb, is he seriously planning to dissect that toad? And the most unbelievable thing is that Seito gives Sky a thumbs up and an ok hand signal. Chris face-palmed and decided to ignore the two.

Later, Professor Stevenson walks in with a lab a.s.sistant who brought in a big box of apparatus needed for the experiment and I don"t want to get this too boring, let"s skip it.

In the middle of the experiment, a lot of mess happens. For example, the girls who put too little amount of chloroform caused the frog to wake up in the middle of the experiment, jumping all around with their internal organs exposed... Ugh... Never mind about that. At Sky"s side, Chris and Itsuki are dissecting the frog with perfect precision and teamwork and Ai is watching while drawing down the details on a paper, although it looks like a kindergarten drawing but at least she tried. While the other two... "That"s the artery right?" Seito asks while pointing at a spot where blood burst out. "Yes, it"s the artery for sure." said Sky who has the knife in his hand. Chris who is slightly distracted by those two still refusing to believe that they are actually dissecting a giant toad. "But this blood looks a bit weird, don"t you think it"s a bit slimy?" said Seito. "Really?" Then Sky touches the blood. "Ah it is... Eww..." said Sky while smearing that gooey and sticky blood red substance on Seito"s arm. "Argh! What are you doing? This is disgusting!" said so, Seito washes his arm at the nearby water tap, however, he didn"t notice that the water drops remain in the basin that he washed his arm slowly turn slimy and slipped into the water hole as if it could move on its own.

Later that day, at an unknown place, a dead body of a man was found, his body is covered with bruises and badly swollen, his eyes, nose mouth, and eyes are stuffed with gooey and slimy substance...
