I've Never Thought That You're Quite Rebellious When You're Younger

When Himari and Kazuya walked side by side along the hallway to go downstairs, the former couldn't help but look at the latter with a confused yet bewildered look in her eyes. It was obvious that she was thinking of something.

Kazuya couldn't resist laughing. He asked with a grin, "Why are you looking at me like that? Do you think my figure is good? Did you feel shy earlier?"

Himari couldn't deny that she was feeling shy when suddenly Kazuya appeared in front of her shirtless but, because she was shocked by another discovery, the bashfulness was replaced by another shocking feeling.

The image of this man's tattoo kept flashing in her mind.

Kazuya had a tattoo on the left side of his shoulders, stretching until the tips reached his lower back. The tattoo was dyed in jet black ink in the shape of a half of fallen angel wings.

But, why just half?

Where was the other half?

And, did the tattoo had any meaning?
