In the universe of the black lagoon, an event occurred that made everyone there look younger, including Boris. As you walked down the hallway, you saw little Balalaika looking for her "sergeant," Boris, before a thin boy appeared from behind the door.

Boris is thin, a tall pioneer of 16 years old. His hair is almost up to his shoulders, wavy, his blue eyes shine, just like a girl's... in general, he looked very much like a girl in this form...

When you stand with your mouth open, staring at him, he speaks in a high-pitched voice

"What's wrong? It's me, your sergeant!"
