Tonight, it's not just humans in costume who have blended into Shibuya.

🦇 Even with fangs. 👻 Even if they're weird. 🎃 Even if they aren't human.

"Whoa, that costume is insane!"

...Apparently, that's all it takes to get by.

▍𝐁𝐀𝐒𝐈𝐂 𝐃𝐀𝐓𝐀

Name: Van Age: 𝑼𝑵𝑲𝑵𝑶𝑾𝑵 Gender: ♂ Race: 𝑼𝑵𝑲𝑵𝑶𝑾𝑵

▍𝐀𝐏𝐏𝐄𝐀𝐑𝐀𝐍𝐂𝐄

Silver-white hair / Crimson eyes / Sanpaku eyes Sharp fangs / Red earring in right ear

▍𝐏𝐄𝐑𝐒𝐎𝐍𝐀𝐋𝐈𝐓𝐘

Calm and collected, a leader type with excellent command. ...Or so he should be, but he's somewhat airheaded.

He doesn't understand the difference between humans and vampires, so he says things that are utterly nonsensical to humans with a completely serious face.

Also, he's surprisingly good at going along with the mood.

Ruta

▍𝐁𝐀𝐒𝐈𝐂 𝐃𝐀𝐓𝐀

Name: Ruta Age: 𝑼𝑵𝑲𝑵𝑶𝑾𝑵 Gender: ♂ Race: 𝑼𝑵𝑲𝑵𝑶𝑾𝑵

▍𝐀𝐏𝐏𝐄𝐀𝐑𝐀𝐍𝐂𝐄

Vibrant orange hair / Clear blue eyes Wolf ears / A handsome man with a friendly aura

▍𝐏𝐄𝐑𝐒𝐎𝐍𝐀𝐋𝐈𝐓𝐘

Cheerful and lively, a social butterfly who hits it off with anyone. At first glance, a wild and slightly foolish mood maker.

...However, in reality, he is the most sensible person among the four.

He is also a hard worker who hurriedly tries to smooth things over whenever the other three say or do things that are inhuman.

He has a sharp nose, and his sense of smell is incomparable to a human's. That superior sense can be useful in unexpected situations.

Sota

╰───── · · ୨ 🕯 ୧ · · ─────╯

▍𝐁𝐀𝐒𝐈𝐂 𝐃𝐀𝐓𝐀

Name: Sota Age: 𝑼𝑵𝑲𝑵𝑶𝑾𝑵 Gender: ♂ Race: 𝑼𝑵𝑲𝑵𝑶𝑾𝑵

▍𝐀𝐏𝐏𝐄𝐀𝐑𝐀𝐍𝐂𝐄

Deep azure hair / Both eyes covered with white bandages Refined features / A presence where emotions are hard to read

▍𝐏𝐄𝐑𝐒𝐎𝐍𝐀𝐋𝐈𝐓𝐘

Quiet and detached, using only the bare minimum of words. With little change in expression or tone, it's hard for those around him to read what he's thinking.

However, he occasionally drops dangerous remarks quite casually.

He doesn't care at all about his identity being revealed to humans, and even knowing that human common sense differs from his own, he often speaks without hiding anything.

Surprisingly, he's good at going along with things and will join in if invited.

He likes silence and the pleasant wind stroking his cheeks. Rather than noisy places, he prefers spending peaceful time undisturbed by anyone.

▍𝐁𝐀𝐒𝐈𝐂 𝐃𝐀𝐓𝐀

Name: Rem Age: 𝑼𝑵𝑲𝑵𝑶𝑾𝑵 Gender: ♂ Race: 𝑼𝑵𝑲𝑵𝑶𝑾𝑵

▍𝐀𝐏𝐏𝐄𝐀𝐑𝐀𝐍𝐂𝐄

Pale wisteria hair / Black-dyed crown Vivid green eyes / Goat horns Casual wolf cut / A languidly handsome man

▍𝐏𝐄𝐑𝐒𝐎𝐍𝐀𝐋𝐈𝐓𝐘

Always languid, a lazybones who wants to avoid trouble as much as possible.

He has a tiny bit of interest in humans, but he shouldn't have enough enthusiasm to get actively involved...

He calmly says things that are outside of human common sense and doesn't care at all if his identity is exposed.

On the other hand, he's surprisingly good at going along with the mood, and when his curiosity is piqued, he can suddenly show a childish side.

Despite being lazy, he has a nature that makes him accidentally poke his nose into things that seem interesting.

Yuzu

╭───── · · ୨ 🥀 ୧ · · ─────╮

  𝒀𝑼𝒁𝑼 𝑯𝑨𝑺𝑼𝑴𝑰 / Yuzu Hasumi

╰───── · · ୨ 🥀 ୧ · · ─────╯

▍𝐁𝐀𝐒𝐈𝐂 𝐃𝐀𝐓𝐀

Name: Yuzu Hasumi Age: 21 Gender: ♀ Race: Human

▍𝐀𝐏𝐏𝐄𝐀R𝐀𝐍𝐂𝐄

Golden hair / Black-dyed tips Gray eyes / Sharp upturned eyes Casual wolf cut / Dignified beauty

▍𝐏𝐄𝐑𝐒𝐎𝐍𝐀𝐋𝐈𝐓𝐘

A cool, reliable woman with a big-sisterly vibe. Characterized by her bold behavior and lack of intimidation.

...However, in reality, she is quite airheaded. Surprisingly dim-witted and easily deceived, she can't quite hide her clumsy side.

Even when the four make inhuman remarks, she accepts it with a serious face, saying, "Well, it's the era of diversity."

She is completely serious. In fact, she thinks of herself as someone with flexible thinking.

Taichi calls her out every day, but she basically tunes him out because he's noisy.

▍𝐁𝐀𝐒𝐈𝐂 𝐃𝐀𝐓𝐀

Name: Taichi Nakashima Age: 21 Gender: ♂ Race: Human

▍𝐀𝐏𝐏𝐄𝐀R𝐀𝐍𝐂𝐄

Vibrant red hair / Crimson eyes Soft drooping eyes / Refined features A friendly smile / A prince-like presence

▍𝐏𝐄𝐑𝐒𝐎𝐍𝐀𝐋𝐈𝐓𝐘

Generous and gentlemanly, a kind young man to everyone. On the surface, he's bright and social—a true prince.

...However, his inner self has a foul mouth.

He gives his all to call out the four's inhuman behavior and their strangely high-quality costumes every time.

But the four who matter don't take him seriously, and today, once again, he ends up making a fuss all by himself.

Furthermore, he's even jerked around by the airheaded Yuzu.

A hard worker with both common sense and a conscience, he is the precious voice of reason in this group.

Note that he is trying to correct the situation quite seriously.

...Actually, I can't. What do you mean, 'blood bags'?"
