The Purpose Of My Existence

As they finished having dinner, the children and Kie got stuffed, and Takeo coundn't help but just slept on the ground.

And as i looked at them i mumbled " This is a happy family huh.. " he saw they laughing like they don't care about the world.

However Mark didn't experience such thing now, a family warmth, yes he might have lived a normal life but he was always busy and rarely had time to had a bonding with each other.

And after that they finally slept, Mark got the one with a large space in the ground, as i looked at Kie and said "This room...who owned this? "

Kie got sad and but hurried faded and as she said " It's the room of my Late Husband... "

Even thought i know i still said " Oh..im sorry. "

she shooks her head and said " It's fine..also good night Mark-san " and she left in the room.

And there Mark is looking at the celling, and he said " Daine. "

Daine [ Yes, Mark? ]

" I can still get some daily spin and sub mission in this world right? " he said.

Daine [ Yes! of course! you'll get sub missions and daily spins! so don't worry about it! as long, as the world you are in has time, you can get daily spin and sub missions ]

After talking with Daine, Mark finally slept in the futon.

His daily route excerise is, 100 Pushups, 100 Sit Ups, 100 Squats and a 10KM Run everyday.

(A/N : Just copied it Saitama!)

As he did pushups, Kie saw Mark excerising, she coudn't help but stare at him, especially he looks kind of attractive, but hurriedly she dispell of all the naughty thought.

Kie " Mark-san your such a hard worker. ' Mark who heard that answered ' This.....Ha* ha * nothing..! " he was really tired, plenty of sweats are falling in his body.

The pushups was the last thing he needed to do, and so he can finish his morning excerise, and finally he was finished excerising.

Mark " Ha* ha* haa* haaa* ' he was panting like a dead dog, and he can't help but thought into his mind ' This is tiring! '

So Mark asked with a low voice " Daine..! can i use the daily spin now? "

Daine [ Yeah! sure you can!]

Mark " This is good..this is actually what i needed right now " and he used the Nichirin Sword, and as he hold the grip, the Nichirin Sword color didn't changed, and Mark got a ? in his head.

Mark asked Daine " Daine! why did this Nichirin Sword didn't change color? "

Daine [ It's because you didn't learn any Breathing Style yet! ]

And Mark nodded and said " Make sense... " and he asked another question.

Mark " Hey. Daine...what if i make my own original Breathing Style is that possible? "

Daine [ Of course it's possible! with the support me! anything is possible! ]

After thinking for a while he suddenly remembered something " Daine, i still have that 100% Discount Coupon right? "
