Even as Another World's BONE KING, I'll still give 50% effort.

[Chapter 8: Before that Day]

Day six, their training session started off quite unique. Haru, who is in his Battleship form, was bombarding them relentlessly with his cannons and nothing more.

He didn't even take the opportunity to attack them while they were all disoriented and blinded by the smoke and dust caused by his battleship cannons.

Touka: How many times is he going to do this?!?

Elleth: Now that you say that, at this point I wouldn't be surprised if this was his go-to move.

Or not, as he immediately deactivated {Fleet} and switched on {Swift Demise} as he ran towards the smoke cloud they were in holding his sword.

In which he fought each of them briefly. A flurry of slashes ending in a heavy overhead slash for Touka, alternating barrage of kicks and slashes for Airi, and roundhouse kick before going into his destroyer form and firing off his torpedoes, acting more like missiles rather than traditional torpedoes, at Elleth.

Once the smoke had cleared, Haru was still standing, not even looking tired, same with the others, just damaged from the attacks that he performed on them.

Haru: Good, good, you three can still keep going.

Just as he finishes his sentence Touka comes flying out, getting in behind him, and just as she's about to pay him back and bring her own swords down on him, he blocks it with his sword.

Touka: My, looks like you can too.

Haru: Would've been dead if I couldn't.

She jumps back as he turns back into his Battleship form, one side's turrets turned towards Touka as the other pointed towards her older sister and Elleth.

Touka: You took that line from a game didn't you?

Haru: Maybe, though are you just sta-

She fires out one of her sword's blades from its hilt, with him having barely managed to dodge it, the blade planting itself into the trunk of a tree nearby as Touka had a grin on her face.

Touka: Now!

She yells out, Airi and Elleth immediately rush towards Haru, taking advantage of the fact that he was caught off guard as the two begin relentlessly attacking him.

He tried to fight back but to no avail as they had knocked away his sword during their assault, along his guns being too slow to rotate and aim at them as they ran around him.

Elleth: How about we speed it up?

Airi: You're on!

Haru: Wait-

The pair started getting faster and faster as Haru continued to struggle to fire his guns at them, trying his best not to use {Skeletal Master} as he still feared using it.

The girls were wearing him down more and more as they continued this one-sided fight. Later on, Touka even joined in, making it even harder for him to fight back.

Their coordination with each other was unparalleled, for Airi and Touka it made sense, they were sisters after all.

Those two being able to pull something like this off wasn't too surprising for him, he knew them since they were kids after all.

Elleth, on the other hand, he definitely didn't expect her to get along with, let alone be able to follow along with them during combat. If anything he expected Airi and her to have a rivalry.

Haru: Ah, damn, I may have created monsters.

He thought to himself, both very proud and very terrified at what he's helped them turn into.
