Chapter 357: Didn't Expect Uncle to Be So Capable

"This is... what?"

"A card you can use to buy stuff," said Rinji. "Of course, only for things available on the market."

"Eh? Really?"

Kei had never seen a card like this before. The number of digits seemed fewer than usual, and instead of ordinary plastic, the card was made of metal.

"Kei, just take it."

Shirogane's father came out from his room with a cup of tea. When he saw the card Rinji handed to Kei, his brows furrowed slightly, then relaxed.

"Eh? Is it really okay?"

"If Uncle says it's okay, then it's definitely okay." Rinji smiled and slipped the card into Kei's hand.

At that moment, Shirogane's father spoke up. "By the way, I overheard you talking to Miyuki about him becoming chairman?"

"Yeah, I want the president to get some hands-on training. I just happened to set up a new company."

"Got a proposal for it?"

"I do."

"Can I take a look? Maybe I can offer some suggestions."

"Sure, I'll go get it from my place."

Rinji nodded, headed to the entrance, put on his shoes, and prepared to run home to fetch the proposal document.

It was just two floors up. Wouldn't take long to get there and back.

After Rinji left, Shirogane papa looked at Kei, who was staring blankly at the black card in her hand, and said, "Kei, that card isn't an ordinary credit card. It's called the 'American Express Centurion Card.'"

"This... what's the difference from a regular card?"

"There's a huge difference." He pointed to the card in Kei's hand. "This card has no spending limit."

"No limit as in...?"

"It means you can spend however much you want."

"Eh!!!?"

This card was known as the "King of Cards," issued in thirty-one countries and regions worldwide. It couldn't be applied for—only invited by the bank. Every cardholder was a billionaire-level figure.

Aside from no limit, it came with top-tier prestige, custom services, and unparalleled global privileges, including round-the-clock concierge services, VIP seats for global events, and access to exclusive private clubs in major cities.

Kei stared blankly at the card in her hand, trembling. Though it was physically light, it felt unbearably heavy.

"So, that's the card," her father said.

"Then why did let Rinji-nii give it to me!?"

"I did not let him give it to you to use," her father replied. "Rinji has known us for a while now, and I understand him. He might seem unreliable on the surface, but he's actually very considerate."

"You have no right to call others unreliable," Miyuki interjected from the side.

"He truly sees us as family. Otherwise, he wouldn't have helped us so many times. He didn't want you two continuing to struggle working to support the family, so he kept helping. If you don't accept this, he might feel like we're rejecting him."

"I... see."

"So just keep the card. It'll also put Rinji at ease," her father said. "But unless it's an emergency, don't use it recklessly."

"...Got it."

"Of course, occasionally using it to buy some inexpensive things is fine. If you never use it at all, Rinji might get the wrong idea."

Her father finished his explanation and calmly sipped his tea.

Shirogane walked over to his sister and saw her still trembling and muttering.

"No limit... anything I want... just because of a word from Rinji-nii..."

"Kei, don't develop bad spending habits!"

"I know... but..."

It was simply too much money.

Especially for a family that had long lived in poverty.

Kei carefully hid the card in her room. Just then, Rinji returned.

"Uncle, I brought the proposal."

"Oh? Let me see."

Shirogane papa pretended as if nothing had happened and accepted the company proposal Rinji handed over.

As he sipped tea and read through it, his brow suddenly furrowed.

"...Rinji."

"Yeah?"

"Did you write this proposal seriously?"

"Of course."

"You sure you weren't just winging it?"

"No way."

"Then... can you explain why the first product for a pharmaceutical company is a biochemical weapon?"

"Because I just happen to have the technology and can find a sales channel."

The sales channel Rinji referred to was obviously IW's internal system. Once produced, the weapons could be directly sold to the organization.

"As a newly founded pharmaceutical company, I don't think the first product should be something like that," Shirogane Papa said seriously.

"You shouldn't even produce medical drugs."

"Huh? Why?"

"In Japan, medical drug profit margins are about 30%, BP products go up to 60%. That's quite high. But think about it—who takes medicine when they're healthy? People only need medicine when they're sick. No one thinks, 'Nice weather today, let me buy some meds.'"

He tapped the proposal.

"Medicine doesn't have customer-attracting capability. Plus, you only have patents and production licenses for specialized drugs, which require connections with hospitals. That's a complicated process. At least in the early stages, don't go that route."

He seemed to get into lecture mode.

"Because of those two disadvantages—low customer draw and high logistical complexity—it's better not to touch advanced medicine early on. I think the company should optimize its product lineup first, produce daily essentials or health supplements, and when the market share is stable, expand with chain stores. The design should use..."

He went on and on, and Rinji patiently listened.

When Shirogane papa finally paused to sip tea, he noticed Rinji looking at him in awe.

"What is it?"

"Nothing... I just didn't expect you to be so amazing."

"This is part of my life experience. Everyone has their prime years."

"Uncle, can I ask you something?"

"Hm?"

"The president ran off already, so why don't you give the company a shot?"
