This character is a Other Letter and is mainly used in the Katakana script.
The glyph is not a composition. Its East Asian Width is wide. In bidirectional text it is written from left to right. When changing direction it is not mirrored. This katakana joins with other adjacent katakana to form a word. U+30CC offers a line break opportunity at its position, except in some numeric contexts.
The Wikipedia has the following information about this codepoint:
Nu, ぬ in hiragana, or ヌ in katakana, is one of the Japanese kana each representing one mora. Both hiragana and katakana are made in two strokes and represent [nɯ]. They are both derived from the Chinese character 奴. In the Ainu language, katakana ヌ can be written as small ㇴ to represent a final n, and is interchangeable with the standard katakana ン.
