Got the idea from Bleach to start working in spiritual power levels. Needs some work, but more or less what I have so far:
 * Minimal: bare minimum, default for humans, not able to see supernatural beings consistently. (Shuji)
 * Low: able to see supernatural beings, but capable of little else. (Toshimori, Yurina)
 * Mid-Range: low to mid-class ability users, most regularly interact with supernatural beings (Yumeko, Sen, Akira)
 * High: very powerful; common for experienced Kekkaishi, mid to high-class ability users; daily interaction with supernatural beings (Masamori, Shigemori, Gen, Rokurou)
 * Enormous: extremely powerful ability users, often viewed as having no equal (Yoshimori, Tokiko, Group of Twelve, Shichirou)
 * Immense: class reserved largely for gods and spirit reservoir owners (Chushinmaru, Mudou, Lord Uro, Sumiko)
