See You Next Year (来年も会いに行きます) is the final stage in Ghostly Strangers.
When the enemy base is damaged, Le'saint spawns as the boss alongside Gabriel, Shy Boy, Angelic Sleipnir and several Ecto Doges, Ecto Snaches and Ecto Baa Baas. After defeating enough of the peons, Lord Enma spawns with 2 Ginger Snaches and Gabriel that constantly respawn. Shy Boy and Angelic Sleipnir respawn 50 seconds after damaging the base.
Le'saint has 1.8 million health and does 36k damage every hit. With Enma, Sleipnirs and Shy Boys helping as support, getting a hit on Le'Saint without the use of Long Distance units will be excruciating, as the Sleipnirs' knockback ability helps the other enemies push. If your Ramen Cat is not at least lvl 45 (57 if you lack Treasures) to tank at least 4 hits from Le'saint, this stage will be extremely difficult, if not impossible without other meatshields and a high amount of Area Attackers. If you do not bring the appropriate units, you'll have to face both Sleipnirs, Lord Enma, and Le'saint all at once, and Le'saint will have to die first before any of the others can be damaged.
