I Have a Treasure Trove - Chapter 487: breakthrough!

When The Cute Kunoichis Spied on Their Teacher's Secret is a light novel written by Kazuma Kamachi and illustrated by Ryuushi Tajima.

The story takes place in a world where Japan never ended their isolationist phase, and agents from foreign powers are always threatening to steal the country's advanced technology. In order to combat this threat there has been a resurgence of ninjas that use Strategic Martial Arts, techniques that combine cutting-edge modern technology with a traditional foundation of martial arts and ninjutsu. The story follows Souha Sugiyado, a 17-year old ninja instructor and former ninja prodigy who was forced to retire from active duty by the wounds he suffered in his last mission. Souha's four students are all kunoichi who have all gained the rank of Elite Ninja, the highest official rank available to ninja. However, one day two Shogunate ninja approach him with the news that his four students have gone rogue and have stolen a portable modular nuclear reactor, and thus they ask for his help in bringing his students to justice.

“While playing a Tsukkur erotic game that I loved, I somehow became possessed. To make things worse, I transformed into a perverted kid—one of the villains from the NTR series.”

Before rebirth, Xia Man had been wondering, when did Qu Zhen begin to hate her?

Was it when she foolishly followed behind her and constantly talked while eating? Or when she would always clumsily break the gifts she was given? So she started hating her?

Did she think such a person was not worthy of being her friend at all? Doesn’t deserve the sunshine?

Right! Sunshine or whatever, it can only be her Qu Zhen!

Xia Man always felt that the friendship between the two people was like Qu Zhen’s alms to herself, never equal.

Xia Man didn’t understand what Qu Zhen meant until she died.

“I thought I never missed it. Now I understand that I’ve never been right.”

Qu Zhen, in a sense, died by Xia Man’s hands, not from a zombie.

Qu Zhen, you could never have been right after doing something wrong. You should never fall in love with a person with a distorted personality.

After Xia Man was reborn, she only wanted one thing.

She wanted those who used her to hurt Qu Zhen to die rather than to live!

Summer, first time down the mountains in 16 years, after being raised by his 3 masters and Fairy sister.

‘Why won’t you follow the Rules of society?’ The rules are the tool made by the strong, so I follow my own rules.

‘Why won’t you just use your brain instead of your brawn?’ Idiot! Have you ever seen anyone use their brain, to get back at an ant that bites them!? No, they just casually step on it.

‘Oh, everyone says you’re a first-class beauty huh?’ well, I’m sorry but even you are not qualified to be my wife. Only a ‘Summer class beauty’ is worthy enough!

‘My enemy is sick?’ Oh, don’t worry, even if you’re on your last breath and I feel it’s beneath me to slap shot you dead. I’ll just fix you up and then beat you!

‘Who am I?’
