  • Can be optionally fought in Breaven, accessed in the bread graveyard(?) to the east of Orange Oasis.

See you, Space Husband…


  • Exclusive to the Hikikomori route. He awaits at the top of Snowglobe Mountain.
  • Gimmicky fight. He starts out frozen and therefore takes only single-digit damage from everything save for the ultimate attack. In order for him to temporarily break out from his ice, one should pay close attention to the dialogue and inflict him with the right emotion whenever he recalls some memories.
  • Start by buffing your team a bit and wait for the turn where he starts recalling a memory. Once you have understood which one he recalls (should be fairly easy to decipher), inflict the corresponding emotion and attack once he breaks out. Rinse and repeat.

The Brightest Stars

– Defeat PLUTO and THE EARTH.

  • Exclusive to the Hikikomori route. Can be found on the path between Capt. Spaceboy’s house and the Junkyard.

The First Law


  • Found in Humphrey after seeing Roboheart fly away, specifically in the final room of the “difficult” puzzle for the bomb in the robotic quadrant.
  • Kind of a joke fight compared to the other two, not hard at all.



  • Exclusive to the Hikikomori route. Found in Humphrey on Day 4 in Headspace, specifically in the same room as Marina (the north room).
  • Kind of a puzzle battle. Mutantheart will name an emotion and will instakill any teammates who aren’t that emotion at the end of the turn. It is useful to have a party member that moves slower than her because she will sometimes alter a mood on her turn and will only instakill after everyone else has moved. Otherwise she doesn’t have a huge health pool and can be beaten pretty quickly.

Minor Imperfection


  • Exclusive to the Hikikomori route. Found in Humphrey on Day 4 in Headspace, specifically in the main lobby of the lower area.
  • The game’s superboss. One should be prepared for an onslaught. See the section in this guide dedicated to her for more specific tips.
