Lina & Gina/Succubus Puttel

Lina and Gina (リナ＆ジナ Rina & Jina) are bosses in Succubus Puttel who are fought as a pair. In versions prior to 3.0, they are also the penultimate bosses of the game.

Profile
''Twin avian succubi who are second only to the queen in power. They normally disguise themselves in the forms of chickens. Either one of them is powerful, but together they can perform incredible sexual techniques. Incidentally, Lina is black and Gina is red.''

Strategy
The main challenge to this battle comes from an external factor: namely, the number of times you've used the Succubus Bird Feather. Lina and Gina become more powerful based on this number. It is therefore best to never use the feather at all. If you've already used it, you can reset the number of uses to 0 by talking to a certain NPC found in 62-chan's Room. However, doing so also resets your level to 1, so it is still best to never use the feather.

For the battle itself, Lina and Gina can do considerable damage as their attacks hit twice. It's a good idea to keep yourself at a higher threshold of Vigor than you normally would, just to be safe. To defeat the twins, use Pussy attacks. Their unique Titjob Restraint skill puts you into a Hold in which your Mouth skills (except for Kiss) are sealed, and is followed by the damaging Twin Titjob, so Struggle out of this Hold as soon as possible if they use this skill.
