''U-M-ARU! U-M-ARU! Hey, it's the hamster, Umaru!''

''U-M-ARU! U-M-ARU! Hey, it's the hamster, Umaru!''

-

You know when the hood comes right around my neck,

it's time; it's time- I'm gonna give zero percent.

You wanna come and join me while I sloth around the house?

Sure, just bring some potato chips.

-

Some might call it a split personality.

Just think of it this way- I have two realities.

I don't wanna work, but can you blame me?

I just wanna sit back and play an RPG.

-

"Walking around the courtyard, she just so delicate.

She'll help anyone, even if she won't benefit.

She's the model student; she's perfect!" Yeah, right!

If you saw my sweet combos, you'd really die of fright!

''So now, it's time to sloth around! (Uh, yeah!)''

-

It's time to eat, sleep,and play and just waste the day away!

''What's that? What's that? Nah, me and games are BFF's.''

Onii-chan may be strict and a bit mean,

but hey; but hey, what's to do you're not perfect?

I may be spoiled and act just like a NEET,

''but, hey. You know life isn't fair.''

''U-M-ARU! U-M-ARU! Hey, it's the hamster, Umaru!''

''U-M-ARU! U-M-ARU! Hey, it's the hamster, Umaru!''

-

''Yeah! Tune in next week!''

''In public, I'm sweet. At home, like a NEET.''

With this smile as a tool to keep this part a secret.

You know I can't let this chibi-form get leaked.

For this split lifestyle no one can ever see.

-

"Everyone sees her as a goddess among men.

Just by looking, she could always win.

''For me? I know she's not a dolphin." Big bro?!''

What do you mean 'mascot to heal other's pain'?!

''I just want a party like no other! (Hey, now look there! It's showtime)''

-

I'll just act adorable so I can get what I want.

Onii-chan can always see through my bluffs with such extreme clarity!

''I guess I could tell him thanks...? No, I can't do it! Cry some more!''

JK!

-

Two hearts beating as one, right?

 'Cuz, 'cuz, that's what siblings are like, right?

''I guess we're two peas in a pod, or in the same boat. Or so I guess.''

-

So today, let's just laugh, as we play a co-op game!

Tighter; tighter, I hold right onto your heart.

Onii-chan, thanks for taking care of me!

So, what about that kitty plush?

Nana, Sylphin, Kirie, you guys wanna hang out?

I'll try to be the best best friend.
