One day, Lu En, a ghost-backed master, appeared in front of Luffy who was shouting to go to sea, and made Luffy cry on the spot.

Luffy: “The pirates in the sea are all monsters like my brother? I don’t want to go out to sea!”

Garp: “For a long time, the two boys, Long and Luffy, with small arms and calves, I really doubt that they are not my sons and grandsons. Like Lu En, they are the grandsons of the old man!”

Warring States: “The strongest creature in the sea, land and air is Kaido? No, it’s Lu En!”

- Description from novelbuddy

First of all, this is not a story where the cannon fodder chambermaid counterattacks and gives the main wife a beat-down! As a lowly s*ave who had been sold a total of six times, Xiao Hua has long become apathetic to her situation. In her past life, she was a cannon fodder chambermaid who was beaten to death. In this life, she decided to turn over a new leaf and live honestly, yet in the end still ended up being sold off. This prince’s estate seems to have pretty good benefits? She could be released at twenty-five, and they’d arrange a place for her to live under their jurisdiction? They’d even get rid of her s*ave records? Great! That’s great! Xiao Hua thus decided to stay in the Jing Prince Estate and do her job properly. It’s a shame she could never overcome the whims of fate…. The master she serves is a “mute boy”, with several influences above him watching like tigers eyeing their prey. To say she doesn’t want to be pampered is definitely a lie. This is the road to survival of a “discreet girl” who clings on to her master’s leg and is solely pampered, yet feels that he never pampers her. The road from a cannon fodder chambermaid to a beloved imperial consort is a little long….

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.

Noah Brown had a gift for fighting. Unfortunately punching things didn't pay the bills, at least until he died and an Eldritch god found his soul. The encounter led him to a new world, summoned by bloody cultists, with nothing but the shirt on his back, and a strange item in his system menu.

[???] : A source of infinite potential.

Perhaps he'd finally get to put his gifts to good use.
