Yamata no Orochi

Yamata no Orochi is/are eight lamias that are all symbolically connected to each other. Stationed at Yamatai Village, she demands male human sacrifices every year to feast on their semen. She is the Eastern member of the “Guardians of the Directions”, the others being Kraken, Sphinx, and Poseidoness, although Yamata no Orochi hasn't gotten the same responsibility.

When Luka arrives at Yamatai Village, the chief explains the situation of the village: every year Yamata no Orochi demands male humans to be sacrificed, or she will destroy the village. The sacrifices are not killed but get severely addicted to her, seen when four men within one of the rooms are arguing who becomes the next sacrifice. Alice and Tamamo pitch in along with the fake hero to help get rid of the issue. The plan is to offer Luka as a sacrifice so he may confront and defeat the menace.

At nightfall, the four men from earlier ambush Luka, trying to prevent him from being the sacrifice, only to either succumb to a wet dream created by Alice, or are chased off, or are sealed. Alice appears and informs Luka that Tamamo left him the Tamamo Ball, and that, like before, she will not assist him. After that, she leaves. The chief then ferries Luka to the hideout of Yamata no Orochi. When Luka draws his sword, she decides to "play" with the sacrifice first.

Luka barely holds out when the Ball forms into Tamamo, who helps him use Gnome's power more effectively. Following her instructions, Tamamo then deals hard-hitting damage on Yamata no Orochi and decides to seal her once and for all.

At the Snake Shrine within Yamatai Village, Shirohebi reveals that Yamata no Orochi in her sealed form is being kept in a small terrarium, so that she can reflect on her past actions.

Monsterpedia Entry
''“An ancient monster who has eight independent heads. She was sealed for 100 years but seems to have awoken recently. Boasting extremely high magical power, she seems to be the most powerful monster in the region.''

''Though she has sexual organs, she is unable to have children. Though she can't produce, she is very lustful. Located in the Yamatai Region, she requires a sacrifice every year. As the sacrifices will be licked dry by her eight heads for a full year, the sacrifices happily volunteer for the role.''

''After the year is up, the sacrifice will be sent back to the village and a new one will take his place. The man that returns comes back disabled and exhausted, but is not killed."''

Battle Overview
Being one of the Guardians of the Directions, she should not be underestimated. She has a large amount of health and has several multi-hitting attacks. At times, she may laugh and do nothing. Despite the evaluation stating Gnome is critical to escape her bind, Sylph has a great chance of evading it as well as the rest of her attacks. However, do not use Death Sword Chaos Star, for she will dodge it completely.

Once some damage is dealt, the Tamamo Ball turns into Tamamo and teaches Luka how to use the power of Gnome, allowing him to use the Breath of the Earth. For interfering, Yamatai no Orochi directs her attacks on Tamamo and constantly strikes with Head Smash, to no avail. Using the earth, he feels that the power has grown. With that, Tamamo decides to play and uses the earth to land a powerful punch on the lamias, confusing her on how a small beast can deal serious damage. Luka is appalled, and when he tries the same with a Normal Attack, the power seems too much for him. Tamamo then strikes again with her tail, and takes the Angel Halo and seals Yamata no Orochi with Earth Rumbling Decapitation.

Alternatively, Luka can whittle down Yamata no Orochi's health down on his own without following the scripted event, however this will take a long time. At the end, Tamamo still seals Yamata no Orochi.

If Luka tries to Surrender or Request at this point, Tamamo will prevent that and tell him to act seriously.

If Luka succumbs, Yamata no Orochi's eight heads lick various parts of his body; his tongue, his face, his nipples, his saliva, his sweat, his tears, and of course his penis. Each time he ejaculates, the tongues continue to slither around all over his body until he is "engulfed" by them a year later. Although she normally releases men, Luka is kept as her semen slave.

Evaluation
''“Not only did you not get rid of her, but you ended up as the sacrifice... Are you sure you didn't go into that trying to be the sacrifice? Now then, Yamata is quite difficult. Under normal circumstances, victory would be impossible. All you need to do is reduce her health a little... But even then, that will be difficult. The most important thing is to escape from her restraint, so Gnome should always be summoned. After that, you should focus on recovery. It's a long battle, so make sure not to get overwhelmed. Take care while recovering, and don't let the fight drag on too long. In addition, that powerful blow that attacks at random won't work... Now go, oh brave Luka. Destroy that evil being that torments the villagers.''“
