Doing Something with my ‘Angel’ Little Sister in Another World

’t show any signs of movements.

It seems like I did kill it this time.

「「….U, UWOOOOOOOOOOOOOOー！！！」」(fishermen)

After a moment of silence, the fishermen cheered again.

I feel sorry that they had to start over the cheering because of me…

Anyway, I won, right? This is my first time killing such a big monster!

Now that I feel relieved, I feel like my power is leaving my body.
I sat down on the ground and enjoyed the sense of fulfillment that I was able to defeat a big and tough monster.

When I was enjoying my victory, Nicola’s voice suddenly echoed in my head, disturbing my blissful time.

『In the end, you kept attacking from a position where the enemy’s attacks can’t reach you, huh? That’s what cowards usually do, but good job, Onii-chan!』(Nicola)

『Oh, shut up.
It’s called “strategy”.』(Mark)

『Anyway, you should have leveled up after defeating such a strong monster.
Do you feel something different with your body?』(Nicola)

『Hmm…..
Ah, now that you mentioned it, I feel something has changed…』(Mark)

It felt weird but I could tell that the amount of my mana has increased, also, my field of vision looked a little clearer than before.

Does this mean I’ve gained the power from the lord’s soul?

「Mark, I knew you could do it.」(Celine)

When I was trying to feel the power of lord’s soul in my body, Celine approached me and gently stroked my head.

「You’re lucky that it was a stupid monster.
I thought it would be more difficult for you.」(Celine)

「This one was quite difficult though…」(Mark)

「Oh, right.
If this monster is this big, I’m sure its magic stone is pretty big too.」(Celine)

Celine approached the lake and jumped onto the top of the lord’s corpse.

After she chanted something, her magic wand in her hand began to glow.
She then effortlessly cut open the lord’s torso with her magic wand and put her hand into it.

After a while of rummaging the lord’s stomach, Celine pulled out her hand.
She was holding something like a big blue jewel in her hand.

She then turned to the boss and called out to him.

「Boss-san, is it okay if Mark keeps this?」(Celine)

「Magic stone, huh? Of course.
We have no right to keep it.
It’s the boy’s.」(the boss)

The boss nodded to Celine with a satisfied face and a cheerful smile.

Celine then jumped off the lord’s corpse and handed the magic stone to me.

「Here.
It’s yours.」(Celine)

「Thank you.」(Mark)

So this is The Lord of Secard Lake’s magic stone, huh?

Magic stones are stones containing mana that are used for making magic tools.
The ones from weak monsters such as goblins and kobolds mostly have no value, so people don’t usually keep magic stones from weak monsters, but this one is different.

I’ve seen a magic stone before from a broken magic tool, but that was as small as my fingertip.
However, this one is about the size of an adult’s fist and it has a very clear and beautiful blue color.

I don’t know how much it’s worth exactly, but I’m pretty sure this is quite expensive.

Should I sell it? I don’t know how to use a magic stone after all.

When I was wondering about what I should do with the magic stone, suddenly tiredness began to assault my body.
Looks like all the tension began to disappear from my body.

I feel really sleepy right now…

I put the magic stone in my item box, leaned against Celine’s body and closed my eyes.

「Celine, I leave the rest to you…」(Mark)

「Fufu.
Okay, good night~」(Celine)

I fell asleep as soon as I felt Celine’s warm and soft body…
