Serina Leaf is a heroine in Conception 2. She is not available from the start of the game, becoming available after the first Dusk Circle is sterilized. She is the fifth heroine that the protagonist meets while at the Academy. Serina is a typical tsundere, being hostile and rude towards the protagonist at first- this changes as the protagonist bonds with her and gains her trust. Her main weapon is the Exiv Cannon; a "kick gun" that fires energy as projectiles. It is later upgraded with the Supernova Superchip, becoming Helios.
