Nessie (Bat)

Nessie is the weapon most associated with Seiko Ayase. It is a metal bat with a red handle, carrying the inscription Power of Nessie down its length. Tucked into the bat is a retractable pencil tip, which Seiko relies on for her barrier magic. The name honors the Loch Ness Monster.

Seiko uses the bat first and foremost for striking opponents up close. By channeling the Power of Words into it, she can boost her own strength and magnify the force behind each swing; during a session with Momo, one such hit launched a sandbag flying through the air. The concealed pencil lets her apply her charm nails to draw circles on the ground, raising barriers that ward off evil spirits, either shielding herself from approaching yokai or sealing them in. When trapping a yokai, she rings it in a tight barrier and rains down strikes that are hard to dodge, with every blow knocking the creature past the barrier's edge and setting off its ignition as punishment.

Seiko Ayase is the bat's sole wielder. It got its name during her training with Momo on using the Power of Words: after Momo declared Nessie the strongest creature alive, Seiko inscribed Power of Nessie on the bat and named it for the Loch Ness Monster, then showed off the technique by shouting Nessie at a sandbag with such conviction that it bounced off her house. Years afterward, while training Jiji, Seiko used the bat to explain the idea of spintronics, marking the ground as she spun the weapon to illustrate how a clockwise rotation conserves energy and a counter-clockwise one releases it.
