Chapter 8: Wait, Where's My Romance System?
[Current System Skills: ① Affection Level Check.]
After brief internal complaints, Amano returned to the dinner table.
Since it already happened, no point regretting further or wasting more energy.
Don't cry over spilled milk—Amano's life principle across both lifetimes.
Besides, having something was better than nothing.
Even if the current system only came with one function.
'Affection Level Check.'
Amano silently activated it mentally.
For affection check targets, only the three people at the dinner table besides Amano himself.
So why three people?
Because Yui, that shameless freeloader, actually came to mooch food after seeing Amano score big today!
And she ate more than anyone else!
Though in the current situation, he really should thank Yui a little.
She was the only one among these three suitable for Amano to test the romance system's affection check.
After mental activation, within Amano's vision, a number faintly floated above Yui's head.
[Affection: 68 (Good Friends Level)]
[Insufficient affection to claim rewards. Please host, keep working hard.]
How to put it—though affection wasn't sufficient for Amano to claim rewards, out of 100 maximum points, Yui had 68 points for him. Pretty surprising.
He'd figured based on Yui's usually domineering attitude toward him, having 50-something would be decent.
Turns out 68 points. Unexpectedly high.
According to system prompts, that indicated a very good friendship.
Who knew? Who knew this pink twin-tails was secretly a hidden tsundere type.
"Amano, why are you staring at me?"
Noticing Amano's strange gaze, Yui's stuffed cheeks moved.
"You're not complaining I eat too much, are you? I'm telling you, you can't say something that rude to a lady!"
"You eat too much."
"You jerk!"
[Yui Affection +1, Current Affection: 69]
So you really are a tsundere?
Tsundere mouths tell tsundere lies.
"Just kidding." Amano smiled, adding more food to Yui's bowl. "Eat more~"
"Oh... okay..."
Facing sudden gentleness, the usually aggressive Yui shyly lowered her head, continuing to eat.
This time, affection showed no change.
Women's hearts—so hard to fathom.
Amano figured he definitely couldn't handle this affection system properly.
Since Yui's affection was 69, what about his own sister...
Curiosity driving him, Amano unconsciously glanced toward Shio, who savored her meal with an expression of pure enjoyment.
Sure enough, nothing displayed. After all, this was a romance system—naturally his own sister wouldn't show affection ratings.
Good thing Yui was here, otherwise this affection system would be untestable.
Can't test it... right?
From his peripheral vision, a strange number suddenly crashed into Amano's awareness.
A three-digit number.
Three digits?
Didn't the system say maximum affection was 100?
Above Kikawayu's head clearly displayed—100.
This was Amano's second stone-cold shock of the evening.
Hold up, dude, you?
After repeated observation and verification, Amano confirmed the number above Kikawayu's head was indeed 100.
Affection 100. Maximum points.
[Kikawayu: Affection 100 (Undying Devotion)]
The system's defined highest value—emotion at the level of undying devotion.
Presumably even old married couples would struggle to reach such heights.
Why specifically are you at 100 points? This is a romance system, right?!
Amano suddenly felt a chill down his spine.
"Rei, why do you keep staring at me?"
Amano's excessively 'passionate' gaze—even dense Kikawayu should notice.
Currently biting chopsticks, innocently looking at Amano, Kikawayu's long eyelashes fluttered with pale blue eyes blinking, somehow appearing even...
Cute.
Right, his childhood friend who grew up together was indeed way cuter than other girls.
But no matter how cute, Amano couldn't accept this. Physiologically and psychologically—doubly unacceptable.
However, the next second, a system notification sound completely changed Amano's mindset.
[Pursuable Target Affection Reached 100, Highest-Level Reward Now Available.]
Right—rewards!
Kikawayu, you absolute legend.
Even though Amano struggled accepting Kikawayu having 100 affection points for him, he easily accepted rewards.
Moreover, 100 affection represented the highest-level reward.
But what reward could a romance development system possibly give?
Please don't be anything lewd-related—that would genuinely be useless.
[Highest-Level Reward: Specific Type Extra Deck Full Card Unlock]
What the hell?
This was Amano's third shock of the evening, frozen in place.
You're a romance development system, yet the reward is Yu-Gi-Oh! Extra Deck cards?!
Full circle back around—you were the Duel King System after all!
Just this [Specific Type Extra Deck Full Card Unlock]...
Based on Amano's knowledge, Extra Deck concepts in this world matched Yu-Gi-Oh! anime.
You could place existing cards into your Extra Deck, or create them during duels.
Creation—simply described, this world's Extra Deck allowed 'on-the-spot card printing.'
Just like in the anime.
As long as you met summoning conditions, gained duel spirit recognition, or obtained mainframe Eva's acknowledgment, you could summon monsters not originally in your Extra Deck.
And if this [Romance Development System]'s maximum affection reward was full Extra Deck access, that would be terrifying.
Equivalent to Amano being able to print any card from Yu-Gi-Oh!'s massive database existing in Extra Decks through Main Deck combinations.
Just what did "specific type" mean?
While Amano puzzled over this, a massive roulette appeared before him in the system.
The roulette displayed Yu-Gi-Oh! cards' various type-specific symbols.
Gear symbol represented Machine, axe symbol represented Warrior, triangular hat probably represented Spellcaster.
The arrow-marked roulette spun rapidly before Amano, finally stopping at the last moment.
The arrow landed on the position marked with a dragon head.
[Full Extra Deck "Dragon-Type" Unlocked]
Instantly, hundreds of simultaneous dragon roars seemed to explode in Amano's mind.
Even though not currently dueling, this sensation of being granted power made Amano clearly understand—
He could now use all Dragon-type monsters existing in Extra Decks throughout this world's millennia of card game history.
So you really were a Duel King System disguised as a romance development system.
Why go through all this unnecessary trouble?
