This Is Common Sense, My Dear Friend

"Boom!"

After a loud crash, a seemingly solid wall was smashed open, and a person, soaking wet, crawled out. Ignoring the screaming couple clinging to each other behind him, he ran forward without stopping.

Behind him was a massive whale tail disproportionate to his body. Though curled, it still possessed a beauty born of violence, a raw violence that forced the disturbed couple to swallow the insults that were about to spill from their mouths.

Jilan's body was tied to Isana's fishtail, but even with his body bound, he remained calm and asked, "Are you running so fast to escape? Are you hiding from the captain and the others?"

"There's nothing to be ashamed of, ah, that's right, I'm running away." Zoina swung her whale tail in front of her again, like a warhammer, smashing it open the wall in front of her once more. Jilan's head was enveloped by the soft and elastic fish tail; although he wasn't hurt, he was still completely disoriented. "But you're a prisoner now, I don't give you the right to speak."

"I've always had a question: how did you find me?" Jilan ignored his threat and continued calmly, "Although I did contact the headmaster, that was over a month ago. I don't think I still smell like a rabbit. By the way, I'm a germaphobe. If I were to come into contact with something like your fishy smell, I would definitely wash it off."

"It's no big deal to tell you. I once lost to that rabbit, and he took something very precious from me," Isana said as she ran. "That rabbit seemed very interested in that thing, and it always carried it with it. That thing has a special fragrance that clings to anyone it comes into contact with, and it can't be eliminated even after a long time. I can smell it from a great distance. However, I've always lived at sea, and that rabbit never comes to sea, so this is the first time I've smelled this scent that belongs to me."

"Whale, your true form should be a whale." Jilan calmly looked directly at Zoina. "And if I'm not mistaken, you should also be the largest toothed whale ever discovered in the world, a sperm whale."

"Interesting, where's the evidence?"

"Ambergris." Jilan smiled confidently. "What the headmaster took from you must be ambergris, the undigested excrement from an Ambergris whale, right? No wonder I once smelled an indescribable fragrance on the headmaster; that unique, delicate scent truly befits a top-grade medicinal herb..."

"Did I describe it in too much detail...?" Zoina frowned and murmured softly, "Not speaking to humans for a long time really drives people crazy. Even I become a chatterbox..."

"There's one more thing. Don't you think it's a bit too quiet right now?"

Strangely enough, he had a smooth journey. Apart from some tourists who ran away when they saw him and some waiters who wanted to ask questions but were scared away, none of the Pro Hero he expected came to stop him, even though he had prepared to force his way out.

Moreover... there were no alarms or announcements on the ship; it was eerily quiet, as if nothing had happened.

However, regardless of the circumstances, this situation is advantageous to him.

"You're too noisy." Isana didn't let Jilan continue. Her fishtail transformed into tentacles and shoved towards Jilan's mouth. They had already reached the deck, and it would only take about a minute for her to jump into the water with Jilan. This was only because the ship was so big; otherwise, at her speed, she would have arrived there long ago.

Suddenly, Isana felt a numbness in her fishtail, and the muscles in her tail loosened, causing it to droop limply out of control.

Jilan's arm, which had been trapped in the fishtail, had somehow regained its freedom. He tightly gripped the tentacle that was attacking his mouth and smiled, saying, "Hey, I'm not some magical girl who needs to be bound to give people fan service. Tentacles won't do any good against me."

Isana's gaze sharpened, and the tuft of purplish-black fish tail that had transformed into tentacles suddenly seemed to swell, as if it would break free from Jilan's restraints and become even larger and blacker in the next moment!

However, Jilan's hand, which was gripping the tentacle, shimmered with golden Hamon like lightning, and the purplish-black tentacles, which had just begun to grow, shrank again and became limp.

"I don't want that thing to get bigger in front of me, after all, I'm a germaphobe..." Jilan smiled slightly, "So, you don't mind if I use some physical means to soften it, right?"

Isana didn't reply. The next moment, the curled fish tail that Jilan hadn't touched instantly grew larger, and like a tennis racket, it slammed Jilan away!

Jilan lowered her arm, which had been covering her face with Hamon, and the scrapes healed at a visible speed. Jilan looked up and said, "Sorry, the same move won't work twice against a Saint."

"..." Isana retracted her fishtail behind her back, finally looking Jilan in the eye this time. After a moment of silence, she spoke, "You deliberately brought me to a place like this before making trouble, because... you didn't want the other passengers to be affected?"

"That's partly true, but the main issue is that we didn't have a stage to showcase it back then. The sense of ceremony is the most important part..." Jilan spread her arms and smiled, "Don't you think this place is perfect for us to have an unfinished duel?"

They were currently on an empty deck. Rain had started to fall, dripping and soaking the deck. Thunder rumbled in the gloomy sky, and the sea seemed to be in fury, its waves roaring and churning. No one wanted to come out in this awful weather. But even such terrible weather didn't affect the luxurious ship. The sea's rage was like a rocking baby's cradle, only lulling the passengers to sleep.

"You think that without those annoying tables and chairs, those idiots would only benefit you...?" Zoina sneered. "I have the Quirk of a sperm whale, the ruler of this ocean. You're courting death!"

Isana sneered, "You probably didn't expect this, did you? With so much rain, I can break free of my restraints."

Jilan pointed at Zoina: "Your next line will be, 'Finally, we can take this damn ventilator off!'"

"Finally, I can take this damn ventilator off!"

"... What!?" Zoina's hand, which was resting on the diving helmet covering half of her face, froze. Her eyes were fixed on Jilan: "How do you even know something like this!"

No one knew that the diving helmet on Zoina's face was actually a breathing machine except for himself, not even the rabbit that defeated him. So why did this guy in front of him know?

Jilan smiled and looked at the other person with an expression that seemed to be looking at "wisdom".

"That's common sense, my dear friend."
