"Teigu and Shingu are extremely powerful relics that can evolve with the user, but the requirements and limitations are too much. Only Esdeath, Merraid, Tsukushi, Akame and Kuromi have evolved, but their weapons can still be broken or the side effects are too much that their bodies can't handle it. I am trying to find a new way to improve the weapons or to help their bodies become stronger," "Green said
"I can't help much, but I think this definitely will," Katsu said after thinking for a while, taking out a pill gifted by Shiho. In her world, this pill is the original product that gives superpowers to people, but leads to unstable emotions. Her world didn't have any special material like Danger Beasts, so this was created purely by science, so combining with Danger Beasts may give it unexpected results in improving the human body.
Green takes the pill with interest after hearing the confident tone from Katsu. Katsu leaves the room, knowing Green will be busy for a long time.
He arrived at a training ground to see Akame, Kurome sparring with Esdeath. Akame and Kurome don't like fighting much but because they are in the Assassination Division of the Empire, when there isn't any target, they usually have a lot of free time eating or hunting, so Esdeath usually finds the two to "train".
She also has a lot of free time, letting her personal bodyguards and the strongest group in her army, known as the "Three Beasts", do all the "unnecessary" work for her. She is only active when there is a large battle or invasion, letting her satisfy her bloodlust. In those free times, she used to battle other members of the group or torture her enemy for intel and train her army.
She also intentionally limits herself to enjoying the battle when fighting Akame and Kurome. She only used her sword, but the number of times she asked them for battle really drained Akame and Kurome's mentality a lot, so when they saw Katsu they happily let him spend time with her while the two escaped, probably finding a Danger beast to hunt to satisfy their hunger.
"Perfect time Katsu I have something to show you" she takes out a strange pendant and activates it teleporting him and her to an island.
"I have been preparing for this a long time after acquiring the Shambhala from Honest son corpse so this is our first honeymoon" Esdeath blushed as she hold his hand.
His brain is a mess as all of this happens too fast making him a bit nervous.
"Hmm? I didn't expect to see this reaction from you Katsu, you always tried to act calm but you are quite cute like this" she chuckles caressing his face.
Feeling her warm hand he suddenly pulls her toward him and kisses her soft lips.
"That was for teasing me" he smiled looking at Esdeath whose face has turned completely crimson.
"Since you prepare so much let's enjoy our stay then"
