Certain Tabegami can either evolve or Taste Change if you the meet their requirements. Both methods require you have the necessary item (soul ingredients) and some gold.
Example: To evolve Curine (Fighter-type) into Marines Curine (Fighter-type), you’ll need the item “Marines Spice”. Evolution items are always indicated with a red background. Evolution can only be performed once and cannot be reversed afterwards.
Example: To Taste Change Curine (Fighter-type) into Hot Curine (Tricker-type), you’ll need the item “Hot Curine Spice”. Taste Change items are also indicated with a red background. If you wish to change Hot Curine back into Curine, you'll need the item “Curine Spice”. Unlike evolution, Taste Change can be performed as many times as you wish provided you have enough of the needed items.
Where to go to perform evolution or Taste Change:
When viewing the Tabegami box menu, press X to switch over to the 2nd menu tab. You’ll see which of your Tabegami are currently eligible for evolution or taste change.
Selecting a Tabegami will bring up a submenu detailing all their options for evolution and Taste Change. Your Tabegami will need to reach maximum level and you must own their required item. If you do, you’ll see a purple CLEAR sign. If you don’t, a message will appear.
レベル・魂食材が足りないため進化することができません: Cannot evolve due to lack of level and soul ingredients. (A similar message can appear for just not having a high enough level or just lacking the specific soul ingredient.)
デッキにセットされているため進化することができません: Cannot evolve because it is set in your deck.
1度「進化」したタベガミをもラー度進化させることはできません: A Tabegami that has been evolved once cannot be evolved again.*
When you’ve met all requirements and wish to proceed with an evolution or Taste Change, a screen showing what stat/type changes will occur when the process is complete.
The game will show you how many of the soul ingredient and gold you’ll still have after finishing the evolution/Taste Change.
Finish the minigame and you’ll have completed the process!
*1度「進化」したタベガミをもラー度進化させることはできません: A Tabegami that has been evolved once cannot be evolved again.
For example, this is the entire Ramen Tabegami evolutionary line: (1-Star) Men’nyan, (2-Star) Nyanfumen, (3-Star) Raimen, (4-Star) Raiko.
However, if you have Men’nyan and want to eventually evolve it up to Raikou, you cannot. You can only evolve Men’nyan to Nyanfumen; you won’t be allowed to evolve it again. (Nyanfumen is eligible for Taste Change however.) To get Raiko, you’d need to summon Raimen and then evolve it to Raiko.
